This document was created in an effort to have a single guide to follow for upgrading ISE from 1.3 or 1.4 to version 2.1

 

 

Preparation

 

Create Repository and Copy the Upgrade Bundle

 

Create a repository to obtain backups and copy the upgrade bundle. We recommend that you use FTP for better performance and reliability. Do not use repositories that are located across slow WAN links.

 

For upgrade, you can copy the upgrade bundle to the Cisco ISE node's local disk using the following command:

 

copy ftp://<ipaddress>ise-upgradebundle-1.3.x-and-1.4.x-to-2.1.0.474.x86_64.tar.gz disk:/

 

 

For example,

copy ftp://10.1.100.6ise-upgradebundle-1.3.x-and-1.4.x-to-2.1.0.474.x86_64.tar.gz disk:/

 

Note that there is not a space between the IP address and the file name. The only spaces in the command are shown here:

ftp://10.1.100.6ise-upgradebundle-1.3.x-and-1.4.x-to-2.1.0.474.x86_64.tar.gz

 

Having the upgrade bundle in the local disk saves time during upgrade. The application upgrade prepare command copies the upgrade bundle to the local disk and extracts it.

 

Backup Configuration and Operational Data from the ISE Primary Administration Node

 

Obtain a backup of the Cisco ISE configuration and operational data from the Command Line Interface (CLI) or the GUI.

The CLI command is:

 

backup backup-name repository repository-name {ise-config | ise-operational} encryption-key {hash | plain} encryption-keyname

 

 

Back Up System Logs from the Primary Administration Node

Obtain a backup of the system logs from the Primary Administration Node from the Command Line Interface (CLI). The CLI command is:

 

backup-logs backup-name repository repository-name encryption-key { hash | plain} encryption-key name

 

 

 

Export Certificates and Private Keys

 

We recommend that you export:

  • All local certificates  along with their private keys to a secure location - from all the nodes in your deployment!. Record the certificate configuration (what service the certificate was used for).
  • All certificates from the Trusted Certificates Store of the Primary Administration Node. Record the certificate configuration (what      service the certificate was used for).

 

Backup and Restore of Cisco ISE CA Certificates and Keys

 

You must back up the Cisco ISE CA certificates and keys securely. The Cisco ISE configuration backup does not include the CA certificates and keys. Instead, you should use the Command Line Interface (CLI) to export the CA certificates and keys to a repository and to import them. The application configure ise command now includes export and import options to backup and restore CA certificates and keys.

 

The following certificates from the Trusted Certificates Store are restored on the Secondary Administration Node:

  • Cisco ISE Root CA certificate
  • Cisco ISE Sub CA certificate
  • Cisco ISE Endpoint RA certificate
  • Cisco ISE OCSP Responder certificate

 

You must backup and restore Cisco ISE CA certificates and keys when you:

  • Have a Secondary Administration Node in the deployment
  • Replace the entire Cisco ISE CA root chain
  • Configure Cisco ISE root CA to act as a subordinate CA of an external PKI
  • Upgrade from Release 1.2 to a later release
  • Restore data from a configuration backup. In this case, you must first regenerate the Cisco ISE CA root chain and then backup and restore the ISE CA certificates and keys.

 

 

 

Export Cisco ISE CA Certificates and Keys

 

You must export the CA certificates and keys from the PAN to import them on the Secondary Administration Node. This option enables the Secondary Administration Node to issue and manage certificates for endpoints when the PAN is down and you promote the Secondary Administration Node to be the PAN.

 

Ensure that you have created a repository to store the CA certificates and keys.

 

  1. Enter application configure ise command from the Cisco ISE CLI.
  2. Enter 7 to export the certificates and keys.
  3. Enter the repository name.
  4. Enter an encryption key.

 

 

A success message appears with the list of certificates that were exported, along with the subject, issuer, and serial number.

Example:

The following 4 CA key pairs were exported to repository 'sftp' at 'ise_ca_key_pairs_of_ise-vm1':

Subject:CN=Cisco ISE Self-Signed CA of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x621867df-568341cd-944cc77f-c9820765

 

Subject:CN=Cisco ISE Endpoint CA of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x7027269d-d80a406d-831d5c26-f5e105fa

 

Subject:CN=Cisco ISE Endpoint RA of ise-vm1

Issuer:CN=Cisco ISE Endpoint CA of ise-vm1

Serial#:0x1a65ec14-4f284da7-9532f0a0-8ae0e5c2

 

Subject:CN=Cisco ISE OCSP Responder Certificate of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x6f6d4097-21f74c4d-8832ba95-4c320fb1

 

ISE CA keys export completed successfully

 

 

Import Cisco ISE CA Certificates and Keys

 

After you register the Secondary Administration Node, you must export the CA certificates and keys from the PAN and import them in to the Secondary Administration Node.

  1. Enter application configure ise command from the Cisco ISE CLI.
  2. Enter 8 to import the CA certificates and keys.
  3. Enter the repository name.
  4. Enter the name of the file that you want to import.
  5. Enter the encryption key to decrypt the file.

 

A success message appears.

Example:

The following 4 CA key pairs were imported:

 

Subject:CN=Cisco ISE Self-Signed CA of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x621867df-568341cd-944cc77f-c9820765

 

Subject:CN=Cisco ISE Endpoint CA of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x7027269d-d80a406d-831d5c26-f5e105fa

 

Subject:CN=Cisco ISE Endpoint RA of ise-vm1

Issuer:CN=Cisco ISE Endpoint CA of ise-vm1

Serial#:0x1a65ec14-4f284da7-9532f0a0-8ae0e5c2

 

Subject:CN=Cisco ISE OCSP Responder Certificate of ise-vm1

Issuer:CN=Cisco ISE Self-Signed CA of ise-vm1

Serial#:0x6f6d4097-21f74c4d-8832ba95-4c320fb1

Starting ISE Certificate Authority Service...

 

ISE CA keys import completed successfully

 

 

Obtain Active Directory and Internal Administrator Account Credentials

 

If you use Active Directory as your external identity source, ensure that you have the Active Directory credentials and a valid internal administrator account credentials on hand. After upgrade, you might lose Active Directory connections. If this happens, you need the ISE internal administrator account to log in to the Admin portal and Active Directory credentials to rejoin Cisco ISE with Active Directory.

 

Activate MDM Vendor Before Upgrade

 

If you use the MDM feature, then before upgrade, ensure that the MDM vendor status is active.

Otherwise, the existing authorization profiles for MDM redirect are not updated with the MDM vendor details. After upgrade, you must manually update these profiles with an active vendor and the users will go through the onboarding flow again.

 

Record Profiler Configuration

 

If you use the Profiler service, ensure that you record the profiler configuration for each of your Policy Service nodes from the Admin portal (Administration > System > Deployment > <node> > Profiling Configuration). You can make a note of the configuration or obtain screen shots.

 

 

Upgrading

 

Upgrading a Distributed Deployment

You must first upgrade the Secondary Administration Node to the new release. For example, if you have a deployment setup as shown in the following figure, with one Primary Administration Node (node A), one Secondary Administration Node (node B), one Inline Posture Node (IPN) (node C), and four Policy Service Nodes (PSNs) (node D, node E, node F, and node G), one Primary Monitoring Node (node H), and one Secondary Monitoring Node (node I), you can proceed with the following upgrade procedure.

Upgrading1.jpg

 

 

Note:

Do not manually deregister the node before an upgrade.

Use the application upgrade prepare and application upgrade proceed commands to upgrade to the new release. The upgrade process deregisters the node automatically and moves it to the new deployment. If you manually deregister the node before an upgrade, ensure that you have the license file for the Primary Administration Node before beginning the upgrade process. If you do not have the file on hand (if your license was installed by a Cisco partner vendor, for example), contact the Cisco Technical Assistance Center for assistance.

 

 

To upgrade your deployment with minimum possible downtime while providing maximum resiliency and ability to roll back, the upgrade order should be as follows:

 

  1. Secondary Administration Node (the Primary Administration Node at this point remains at the previous version and can be used for rollback, if upgrade fails.
  2. Primary Monitoring Node
  3. Policy Service Nodes.   At this point, verify if the upgrade is successful and also run the network tests to ensure that the new deployment functions as expected. See Verifying the Upgrade Process for more information. If the upgrade is successful, proceed to upgrade the following nodes:
  4. Secondary Monitoring Node
  5. Primary Administration Node.    Re-run the upgrade verification and network tests after you upgrade the Primary Administration Node.

 

Before You Begin

If you do not have a Secondary Administration Node in the deployment, configure a Policy Service Node to be the Secondary Administration Node before beginning the upgrade process.

Ensure that you have read and complied with the instructions given in Preparing for the Upgrade.

When you upgrade a complete Cisco ISE deployment, Domain Name System (DNS) server resolution (both forward and reverse lookups) is mandatory; otherwise, the upgrade fails.

 

Step 1  Secondary Administration Node

 

Upgrade the Secondary Administration Node (node B) from the CLI.

The upgrade process automatically deregisters node B from the deployment and upgrades it. Node B becomes the primary node of the new deployment when it restarts. Because each deployment requires at least one Monitoring node, the upgrade process enables the Monitoring persona on node B even if it was not enabled on this node in the old deployment. If the Policy Service persona was enabled on node B in the old deployment, this configuration is retained after upgrading to the new deployment.

 

Step 2  Primary Monitoring Node

 

Upgrade one of your Monitoring nodes (node H) to the new deployment.

 

We recommend that you upgrade your Primary Monitoring Node before the Secondary Monitoring Node (this is not possible if your Primary Administration Node in the old deployment functions as your Secondary Monitoring Node as well). Your primary Monitoring node starts to collect the logs from the new deployment and you can view the details from the Primary Administration Node dashboard.

If you have only one Monitoring node in your old deployment, before you upgrade it, ensure that you enable the Monitoring persona on node A, which is the Primary Administration Node in the old deployment. Node persona changes result in a Cisco ISE application restart. Wait for node A to come up before you proceed. Upgrading the Monitoring node to the new deployment takes longer than the other nodes because operational data has to be moved to the new deployment.

 

If node B, the Primary Administration Node in the new deployment, did not have the Monitoring persona enabled in the old deployment, disable the Monitoring persona on it. Node persona changes result in a Cisco ISE application restart. Wait for the Primary Administration Node to come up before you proceed.

 

Step 3  Policy Service Nodes

 

Upgrade the Policy Service Nodes (nodes D, E, F, and G) next.

 

You can upgrade several PSNs in parallel, but if you upgrade all the PSNs concurrently, your network will experience a downtime.

If your PSN is part of a node group cluster, you must deregister the PSN from the PAN, upgrade it as a standalone node, and register it with the PAN in the new deployment.

 

After the upgrade, the PSNs are registered with the primary node of the new deployment (node B), and the data from the primary node (node B) is replicated to all the PSNs. The PSNs retain their personas, node group information, and profiling probe configurations.

 

Step 4   Inline Posture Node (IPN)

 

Deregister the IPN node (node C) from the Primary Administration Node.

 

Note: Cisco ISE 2.0 and later does not support IPN nodes!

 

Step 5  Secondary Monitoring Node

 

If you have a second Monitoring node (node I) in your old deployment, you must do the following:

  1. Enable the Monitoring persona on node A, which is the primary node in your old deployment.

    A deployment requires at least one Monitoring node. Before you upgrade the second Monitoring node from the old deployment, enable this persona on the primary node itself. Node persona changes result in a Cisco ISE application restart. Wait for the primary ISE node to come up again.
  2. Upgrade the Secondary Monitoring Node (node I) from the old deployment to the new deployment.

 

Except for the Primary Administration Node (node A), you must have upgraded all the other nodes to the new deployment.

 

Step 6  Primary Administration Node

 

Finally, upgrade the Primary Administration Node (node A).

 

This node is upgraded and added to the new deployment as a Secondary Administration Node. You can promote the Secondary Administration Node (node A) to be the primary node in the new deployment.

 

After the upgrade is complete, if the Monitoring nodes that were upgraded contain old logs, ensure that you run the application configure ise command and choose 5 (Refresh Database Statistics) on the Monitoring nodes.

 

 

Complete flow of a Successful Node Upgrade

 

Here is an example CLI transcript of a successful secondary Administration node upgrade.

 

Step 1   Create a repository on the local disk.

For example, you can create a repository called "upgrade."

 

ise/admin# conf t

Enter configuration commands, one per line.End with CNTL/Z.

ise/admin(config)# repository upgrade

ise/admin(config-Repository)# url disk:

% Warning: Repositories configured from CLI cannot be used from the ISE web UI and are not replicated to other ISE nodes.

If this repository is not created in the ISE web UI, it will be deleted when ISE services restart.

ise/admin(config-Repository)# exit

ise/admin(config)# exit

Step 2   Prepare the Node for Upgrade

From the Cisco ISE command line interface (CLI), enter application upgrade prepare command.

This command copies the upgrade bundle to the local repository "upgrade" that you created in the previous step and lists the MD5 and SHA256 checksum.

 

ise/admin# application upgrade prepare ise-upgradebundle-1.3.x-and-1.4.x-to-2.1.0.474.x86_64.tar.gz upgrade

% Please confirm above crypto hash matches what is posted on Cisco download site.

% Continue? Y/N [Y] ? y

Enter Y to continue.

The upgrade package is extracted. The following message appears.

Verifying the Upgrade Process

 

To verify if an upgrade is successful, do one of the following:

  • Check the ade.log file for the upgrade process. To display the ade.log file, enter the following command from the Cisco ISE CLI:
show logging system ade/ADE.log
  • Enter the show version command to verify the build version.
  • Enter the show application status ise command to verify that all the services are running.

 

We recommend that you run some network tests to ensure that the deployment functions as expected and that users are able to authenticate and access resources on your network.

 

If upgrade fails because of configuration database issues, the changes are rolled back automatically.

 

 

Items to Check after Upgrade (Gotchas)

 

After upgrading your deployment, you will want to verify the tasks below to ensure proper functionality of the ISE.

 

Browser Cache

Ensure that you clear the browser cache, close the browser, and open a new browser session before you access the Cisco ISE Admin portal. Supported browsers are:

  • Mozilla Firefox version 39 and later
  • Google Chrome version 43 and later
  • Microsoft Internet Explorer 9.x, 10.x and 11.x
    If you are using Internet Explorer 10.x, enable TLS 1.1 and TLS 1.2, and disable SSL 3.0 and TLS 1.0 (Internet Options > Advanced).

 

Adobe Flash Player 11.1.0.0 or above must be installed on the system running your client browser.

 

The minimum required screen resolution to view the Cisco ISE Admin portal and for a better user experience is 1280 x 800 pixels.

 

Active Directory

Join all Cisco ISE nodes with Active Directory again, if you use Active Directory as your external identity source and the connection to Active Directory is lost. After rejoining, perform the external identity source call flows to ensure the connection.

 

  • After upgrade, if you log in to the Cisco ISE user interface using an Active Directory administrator account, your login fails because Active Directory join is lost during upgrade. You must use the internal administrator account to log in to Cisco ISE and join Active Directory with it.
  • If you had enabled certificate-based authentication for administrative access to Cisco ISE (Administration > Admin Access) before upgrade and used Active Directory as your identity source, after upgrade, you will not be able to launch the ISE login page because Active Directory join is lost during upgrade. If you run in to this issue, from the Cisco ISE CLI, start the ISE application in safe mode using the following command:
application start ise safe

 

Certificate Backups

 

Obtain a backup of the Cisco ISE CA certificates and keys from the Primary Administration Node and restore it on the Secondary Administration Node. This ensures that the Secondary Administration Node can function as the root CA or subordinate CA of an external PKI in case of a PAN failure and you promote the Secondary Administration Node to be the Primary Administration Node.

 

Certificate Root Chain

 

After you upgrade a distributed deployment, the Primary Administration Node's root CA certificates are not added to the Trusted Certificates store when both of the following conditions are met:

Secondary Administration Node (Primary Administration Node in the old deployment) is promoted to be the Primary Administration Node in the new deployment

  • Session services are disabled on the Secondary Administration Node

 

This might result in authentication failures with the following errors:

  • Unknown CA in chain during a BYOD flow
  • OCSP unknown error during a BYOD flow

 

You can see these messages when you click the More Details link from the Live Logs page for failed authentications.

As a workaround, after you upgrade your deployment and you promote the Secondary Administration Node to become the Primary Administration Node in the new deployment, generate a new ISE Root CA certificate chain from the Admin portal (choose Administration > Certificates > Certificate Signing Requests > Replace ISE Root CA certificate chain).

 

Network Access Devices

To view the network device profiles, from the Admin portal, choose Administration > Network Resources > Network Device Profiles.

To apply a network device profile to a NAD:

  1. Choose Administration > Network Resources > Network Devices.
  2. Edit the NAD and select the appropriate profile.

You can easily apply network device profiles to many NADs at a time by exporting the list of NADs, adding the profiles, and then reimporting the NADs.

 

Cisco ISE, Release 2.x introduces support for some non-Cisco Network Access Devices (NADs). If you deployed non-Cisco NADs prior to Release 2.x and created policy rules or RADIUS dictionaries to use them, these will continue to work as usual. ISE 2.x offers several predefined network device profiles that can be applied to non-Cisco devices to support a variety of features such as MAB, dot1x, Change Of Authorization (CoA), and URL redirection to enable flows such as Guest, Posture, and so on. See ISE Third-Party NAD Profiles and Configs for more information.

 

 

RSA SecurID

Reset the RSA node secret if you use RSA SecurID server as your external identity source.

 

Posture Updates

Perform a posture update from the Primary Administration Node after upgrade if you have enabled the Posture service.

 

SNMP

If you had manually configured the Originating Policy Services Node value under SNMP settings, this configuration is lost during upgrade. You must reconfigure this value.

 

Profiler Feed Service

Update the profiler feed service after upgrade to ensure that the most up-to-date OUIs are installed.

From the Cisco ISE Admin portal:

  1. Choose Administration > FeedService > Profiler. Ensure that the profiler feed service is enabled.
  2. Click Update Now.

 

Native Supplicant Profile

Check the native supplicant profile that is used in the client provisioning policy and ensure that the wireless SSID is correct. For iOS devices, if the network that you are trying to connect is hidden, check the Enable if target network is hidden check box in the iOS Settings area.

 

FIPS Compliance

Cisco ISE, Release 2.1 supports the following FIPS-compliant ciphers. TLS versions 1.0, 1.1, and 1.2 are supported.

 

  • For EAP-TLS, PEAP, EAP-FAST, EAP-TTLS:
  • DHE_RSA_WITH_AES_256_SHA256
  • DHE_RSA_WITH_AES_128_SHA256
  • RSA_WITH_AES_256_SHA256
  • RSA_WITH_AES_128_SHA256
  • DHE_RSA_WITH_AES_256_SHA
  • DHE_RSA_WITH_AES_128_SHA
  • RSA_WITH_AES_256_SHA
  • RSA_WITH_AES_128_SHA
  • For EAP-FAST Anonymous Provisioning:
  • ADH_WITH_AES_128_SHA

 

Cisco ISE, Release 2.1 does not support non-FIPS compliant ciphers. The following ciphers are not supported:

  • RSA_DES_192_CBC3_SHA
  • EDH_RSA_DES_192_CBC3_SHA
  • EDH_DSS_DES_192_CBC3_SHA
  • RSA_RC4_128_SHA
  • RSA_RC4_128_MD5
  • EDH_RSA_DES_64_CBC_SHA
  • EDH_DSS_DES_64_CBC_SHA
  • RSA_RC4_128_SHA

 

If you have legacy devices that use these deprecated ciphers, contact the Cisco Technical Assistance Center for support.

 

System Settings

Reconfigure e-mail settings, favorite reports, and data purge settings.

 

Alarms

Check the threshold and/or filters for specific alarms that you need. All the alarms are enabled by default after an upgrade.

 

Reports

Customize reports based on your needs. If you had customized the reports in the old deployment, the upgrade process overwrites the changes that you made.

 

The upgrade software performs some validations. If upgrade fails, follow the instructions provided on screen to recover and successfully upgrade to Release 2.1.

 

Upgrade Failures

At times, upgrade fails because of not following the order in which the nodes have to be upgraded, such as upgrading the secondary Administration node first. If you encounter this error, you can upgrade the deployment again following the order of upgrade specified in this document.

 

In rare cases, you might have to reimage, perform a fresh install, and restore data. So it is important that you have a backup of Cisco ISE configuration and monitoring data before you start the upgrade. It is important that you back up the configuration and monitoring data even though we automatically try to roll back the changes in case of configuration database failures.

_____________________________________________________________________________________

Upgrade failures that happen because of issues in the monitoring database are not rolled back automatically. You have to manually reimage your system, install Cisco ISE, Release 2.1, and restore the configuration and monitoring data on it.

_____________________________________________________________________________________

 

 

Configuration and Data Upgrade Errors

This section describes some of the known upgrade errors and what you must do to recover from them.

 

During upgrade, the configuration database schema and data upgrade failures are rolled back automatically. Your system returns to the last known good state. If this is encountered, the following message appears on the console and in the logs:

% Warning: The node has been reverted back to its pre-upgrade state.

error: %post(CSCOcpm-os-1.4.0-205.i386) scriptlet failed, exit status 1

% Application upgrade failed. Please check logs for more details or contact Cisco Technical Assistance Center for support.

If you need to remediate an upgrade failure to get the node back to the original state, the following message appears on the console. Check the logs for more information.

% Warning: Do the following steps to revert node to its pre-upgrade state."

error: %post(CSCOcpm-os-1.4.0-205.i386) scriptlet failed, exit status 1

% Application upgrade failed. Please check logs for more details or contact Cisco Technical Assistance Center for support.

If there are any validation errors, which is not an actual upgrade failure, the following message appears. For example, you might see this error if you attempt to upgrade a PSN before the secondary PAN is upgraded or if the system does not meet the specified requirements. The system returns to the last known good state. If you encounter this error, ensure that you perform the upgrade as described in this document.

 

STEP 1: Stopping ISE application...

% Warning: Cannot upgrade this node until the standby PAP node is upgraded and running. If standbyPAP is already upgraded

and reachable ensure that this node is in SYNC from current Primary UI.

Starting application after rollback...

 

% Warning: The node has been reverted back to its pre-upgrade state.

error: %post(CSCOcpm-os-1.4.0-205.i386) scriptlet failed, exit status 1

% Application upgrade failed. Please check logs for more details or contact Cisco Technical Assistance Center for support.

If the ADE-OS or application binary upgrade fails, the following message appears when you run the show application status ise command from the CLI following a reboot. You should reimage and restore the configuration and operational backups.

 

% WARNING: An Identity Services Engine upgrade had failed. Please consult logs. You have to reimage and restore to previous version.

 

For any other types of failures (including cancellation of the upgrade, disconnection of the console session, power failure, and so on), you must reimage and restore the configuration and operational backup depending on the personas enabled on the node originally.

The term, reimage, refers to a fresh installation of Cisco ISE. For Monitoring database upgrade (schema + data) errors, you must reimage and restore the configuration and operational backups. Before you reimage, ensure that you generate a support bundle by running the backup-logs CLI command and place the support bundle in a remote repository in order to help ascertain the cause of failure. You must reimage to the old or new version based on the node personas:

  • Secondary Administration Node—Reimage to the old version and restore the configuration and operational backup.
  • Monitoring Nodes—If the nodes are deregistered from the existing deployment, reimage to the new version, register with the new deployment, and enable the Monitoring persona.
  • All Other Nodes—If there are upgrade failures on the other nodes, the system usually returns to the last known good state. If the system does not roll back to the old version, you can reimage to the new version, register with the new deployment, and enable the personas as done in the old deployment.

    In case of upgrade failures, before you try to upgrade again:

  • Analyze the logs. Check the support bundle for errors.
  • Identify and resolve the problem by submitting the support bundle that you generated to the Cisco Technical Assistance Center (TAC).

 

You can view the progress of the upgrade by logging in via SSH and using the show application status ise command. The following message appears: % NOTICE: Identity Services Engine upgrade is in progress...

 

Upgrade Fails During Binary Install

 

An application binary upgrade occurs after the database upgrade. If a binary upgrade failure happens, the following message appears on the console and ADE.log:

% Application install/upgrade failed with system removing the corrupted install

 

Solution:    Before you attempt any roll back or recovery, generate a support bundle by using the backup-logs command and place the support bundle in a remote repository.

 

To roll back, reimage the Cisco ISE appliance by using the previous ISO image and restore the data from the backup file. You need a new upgrade bundle each time you retry an upgrade.

  • Analyze the logs. Check the support bundle for errors.
  • Identify and resolve the problem by submitting the support bundle that you generated to the Cisco Technical Assistance Center (TAC).
