Solved: Upgrade CUCM 8.0.2c to 8.5

mohamedrishin · ‎05-02-2011

Hi All,

I am planning for an upgrade to 8.5 from 8.0.2c for a cluster with Pub and Sub. Here is my plan,

1. Take a backup for CUCM

2. Switch off Sub and Install 8.5 on Pub.

3. Restore using the saved backup

4. Apply the licenses

5. Install 8.5 on Sub

Am I missing something?

Thanks in advance for the responses

Hi Mohamed,

Those steps are not required for this type of upgrade

Here are the recommended steps;

Upgrading from Unified CM 6.x or Later by Using the UCSInstall ISO File

Note Release 6.x customers can install this version, but the ccm.exe will not run unless 7.0 software licenses exist on the system.

Because of its size, the UCSInstall iso file, UCOS_8.5.1.10000-26.sgn.iso, comprises three parts:

•UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part1of3

•UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part2of3

•UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part3of3

Procedure

Step 1 From the Software Download page on Cisco.com, download the three UCSInstall iso files.

Step 2 To combine the three files, execute one of the following commands.

Note Because the UCSInstall_UCOS_8.5.1.10000-26 build specifies a nonbootable ISO, the build proves useful only for upgrades. You cannot use this build for new installations.

a. If you have a Unix/Linux system, enter (copy and paste) the following command into the CLI:

cat UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part1of3 UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part2of3 UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part3of3 > UCSInstall_UCOS_8.5.1.10000-26.sgn.iso

b. If you have a Windows system, enter (copy and paste) the following command into the command prompt (cmd.exe):

COPY /B UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part1of3+UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part2of3+UCSInstall_UCOS_8.5.1.10000-26.sgn.iso_part3of3 UCSInstall_UCOS_8.5.1.10000-26.sgn.iso

Step 3 Use an md5sum utility to verify that the MD5 sum of the final file is:

0c32c562fce5b5be5d9b8f01c749b63f UCSInstall_UCOS_8.5.1.10000-26.sgn.iso

Step 4 Continue by following the instructions in the "Upgrading from a Local Source" section or the "Upgrading from a Remote Source" section.

Upgrading from a Local Source

To upgrade the software from local DVD, follow this procedure:

Procedure

Step 1 If you do not have a Cisco-provided upgrade disk, create an upgrade disk by burning the upgrade file that you downloaded onto a DVD as an ISO image.

Note Just copying the .iso file to the DVD will not work. Most commercial disk burning applications can create ISO image disks.

Step 2 Insert the new DVD into the disc drive on the local server that is to be upgraded.

Step 3 Log in to Cisco Unified Communications Operating System Administration.

Step 4 Navigate to Software Upgrades > Install/Upgrade.

The Software Installation/Upgrade window displays.

Step 5 From the Source list, choose DVD.

Step 6 Enter a slash (/) in the Directory field.

Step 7 To continue the upgrade process, click Next.

Step 8 Choose the upgrade version that you want to install and click Next.

Step 9 In the next window, monitor the progress of the install.

Step 10 Perform one of the following procedures:

a. To install the upgrade and automatically reboot to the upgraded partition, choose Reboot to upgraded partition. The system restarts and is running the upgraded software

or

b. To install the upgrade and manually reboot to the upgraded partition at a later time, do the following steps:

1. Choose Do not reboot after upgrade.

2. Click Next.

3. The Upgrade Status window displays the Upgrade log.

4. When the installation completes, click Finish.

5. To restart the system and activate the upgrade, choose Settings > Version; then, click Switch Version.

The system restarts, running the upgraded software.

or

Upgrading from a Remote Source

To upgrade the software from a network location or remote server, use the following procedure.

Note Do not use the browser controls, such as Refresh/Reload, while you are accessing Cisco Unified Operating System Administration. Instead, use the navigation controls that are provided by the interface.

Procedure

Step 1 Put the upgrade file on an FTP or SFTP server that the server that you are upgrading can access.

a. If you have a Cisco-provided upgrade disk, copy the contents of the disk to the remote server.

b. If you downloaded the upgrade files, copy the files you downloaded to the remote server.

Step 2 Log in to Cisco Unified Communications Operating System Administration.

Step 3 Navigate to Software Upgrades > Install/Upgrade.

The Software Installation/Upgrade window displays.

Step 4 From the Source list, choose Remote Filesystem.

Step 5 In the Directory field, enter the path to the directory that contains the patch file on the remote system.

If the upgrade file is located on a Linux or Unix server, you must enter a forward slash at the beginning of the directory path. For example, if the upgrade file is in the patches directory, you must enter /patches

If the upgrade file is located on a Windows server, remember that you are connecting to an FTP or SFTP server, so use the appropriate syntax, including

•Begin the path with a forward slash (/) and use forward slashes throughout the path.

•The path must start from the FTP or SFTP root directory on the server, so you cannot enter a Windows absolute path, which starts with a drive letter (for example, C:).

Step 6 In the Server field, enter the server name or IP address.

Step 7 In the User Name field, enter your user name on the remote server.

Step 8 In the User Password field, enter your password on the remote server.

Step 9 Select the transfer protocol from the Transfer Protocol field.

Step 10 To continue the upgrade process, click Next.

Step 11 Choose the upgrade version that you want to install and click Next.

•If you are upgrading from Cisco Unified Communications Manager Release 6.x or 7.x, the upgrade file has the extension sgn.iso.

Step 12 In the next window, monitor the progress of the download.

Note If you lose your connection with the server or close your browser during the upgrade process, you may see the following message when you try to access the Software Upgrades menu again:

Warning: Another session is installing software, click Assume Control to take over the installation.

If you are sure you want to take over the session, click Assume Control.

If Assume Control does not display, you can also monitor the upgrade with the Cisco Unified Real Time Monitoring Tool.

Step 13 Perform one of the following procedures:

a. To install the upgrade and automatically reboot to the upgraded partition, choose Reboot to upgraded partition. The system restarts and is running the upgraded software

or

b. To install the upgrade and manually reboot to the upgraded partition at a later time, do the following steps:

1. Choose Do not reboot after upgrade.

2. Click Next.

3. The Upgrade Status window displays the Upgrade log.

4. When the installation completes, click Finish.

5. To restart the system and activate the upgrade, choose Settings > Version; then, click Switch Version.

The system restarts, running the upgraded software.

As an FYI you can only ever use the the DRS backup copy to restore to exactly the same (including SR's) CUCM version.

Cheers!
