Call Manger Migration from 9.x to 11.x

[Syed Ali Kabir]

Can we restore the call manger version 9 backup directly into call manager 11.
Can we assign the same IP address and hostname on our new VM Call Manager 11 as we have on Call Manager ver.9
If we are going to install Call Manager version 11 on same cisco hardware where our production call manager ver 9.12 is running , can we face any issue regarding IP address and hostname.

No, you cannot restore backup version of 9.x to 11.x as its not permitted/supported.

Below are some key information to keep in mind while performing any backup/restore.

Caution

Be aware that DRS encryption depends on the cluster security password. If you have changed the security password between the backup and this restore, DRS will ask for the old security password. Therefore, to use such old backups, you must remember the old security password or take a backup immediately after the security password change/reset.

Caution

Do not make any configuration changes to Cisco Unified Communications Manager during a restore until after you have verified that database replication is functioning. Configuration changes include any changes that you make in Cisco Unified Communications Manager Administration, Cisco Unified Serviceability, and the User Option windows.

Important: You can restore the DRS backup from a restricted version only to a restricted version and the backup from an unrestricted version can be restored only to an unrestricted version. Note that if you upgrade to the U.S. export unrestricted version of Cisco Unified Communications Manager, you will not be able to later upgrade to or be able to perform a fresh install of the U.S. export restricted version of this software.

Note

If you are running a DRS restore on a SAML SSO enabled cluster with an OpenAM SSO backed up configuration, or on an OpenAM SSO enabled cluster with a SAML SSO backed up configuration, you will be logged out from the DRS GUI during restore. You can check the DRS restore status from the DRS GUI or from the CLI. To check the status from the DRS GUI, log into the DRS GUI and navigate to estore > Status. To check the status from CLI, execute the utils disaster_recovery status command.

Note

If you are restoring Cisco Unified Communications Manager, ensure that the Cisco Unified Communications Manager version that is installed on the server matches the version of the backup file that you want to restore. If you are restoring Cisco IM and Presence Service, ensure that the version that is installed on the server matches the version from the backup file that you want to restore.

Note

For Cisco Unified Communications Manager restores, make sure that all cluster nodes are running the same version of Cisco Unified Communications Manager. For Cisco IM and Presence restores, make sure that all cluster nodes are running the same version of Cisco IM and Presence Service. If different nodes are running different versions, your backup or restore could fail.

Note

The Disaster Recovery System does not migrate data from Windows to Linux or from Linux to Linux. A restore must run on the same product version as the backup. For information on data migration from a Windows-based platform to a Linux-based platform, see the Data Migration Assistant User Guide before following the steps in this procedure.

Note

When you perform a DRS restore to migrate data to a new server, you must assign the new server the identical IP address and hostname that the old server used. Additionally, if DNS was configured when the backup was taken, then the same DNS configuration must be present prior to performing a restore. For more information about replacing a server, refer to the Replacing a Single Server or Cluster for Cisco Unified Communications Manager guide.

Tip

Beginning with Cisco Unified Communications Manager Release 8.0(1), there is only one upgrade scenario in which you must run the Certificate Trust List (CTL) client after a hardware replacement. You must run the CTL client if you do not restore the subsequent node (subscriber) servers. In other cases, DRS backs up the certificates that you need. For more information, see the “Installing the CTL Client” and “Configuring the CTL Client” procedures in the Cisco Unified Communications Manager Security Guide.

But with the help of Prime Collaboration Deployment (PCD) you can migrate from version 9.x to 11.x. and also can keep the same IP address and host name, but there are some considerations to keep in mind. you can refer below docs for more on the same:

Whether you face issues with the same hostname/IP, depend on your vSwitch/DNS/networking config, if they're going to be in the same network, it's obvious there's going to be issues.

If you use a separate network config, isolated from where the other servers are, no, you should not face any issues.

-I always prefer using PCD for migration for call manager. I recently did one for 9.1 to 11.

-The PCD safely shuts down the old server and brings up new one with same IP and config. 

-If you are planning to bring up a parallel ucm along with prod ucm then I would say configure a separate port group different from prod port group to keep them seperate.

-Other option is give them new ip and new hostname, when you decommission prod VM change ip and hostname for new VM as required.

Hi vijit,

I have one requirement customer is planning to upgrade from 9.x to 11.x.need your assistance.plz let me know how to plan for this request.

[mhdrafi83]

It's migration from one ucs to other ucs.

Start by reading the upgrade guide, and the release notes for CUCM, which contain all you need to know about the upgrade and procedure.
