Upgrading CUCM Call Manager from to 10.5 and above

Cisco Unified Communications Manager upgrade RSA Version-3 keys COP file

This update is a required intermediate step before upgrading to version 10.5 and above if the UCM servers are below version

To improve software integrity protection, new RSA keys are being used to sign Cisco Unified Communications Manager releases and any of their associated updates such as Phone Firmware, Device Packages, DST Updates, Locales, Dialplans, or any other update that can be applied to the system.

Time to complete the update is about two minutes minus preparation time.

Proceed at your own risk! These steps worked for me but I provide no support and take no responsibility for anything that goes wrong!

Step 1: Download ciscocm.version3-keys.cop
Step 2: Copy the upgrade file above to a writeable CD or DVD, or an ISO file if your CUCM is virtual.
Step 3: Insert the new CD or DVD into the disc drive on the local server that is to be upgraded.
Step 4: Open Cisco Unified Communications Operating System Administration directly by entering the following URL:
where server-name is the host name or IP address of the admin server.
Step 5: Enter your OS Administrator username and password.
Step 6: Choose Software Upgrades > Install/Upgrade.
Step 7: For the software location source, choose DVD/CD.
Step 8: If you burned the patch file to a subdirectory on the CD or DVD, enter the path in the Directory field.
Step 9: To continue the upgrade process, click Next.
Step 10: Choose "ciscocm.version3-keys.cop.sgn" and click Next.
Step 11: In the next window, monitor the progress of the download, which includes the filename and the number of
megabytes that are getting transferred.
When the download completes, the Checksum window displays.
Step 12: Verify the checksum value:
Step 13: After determining that the cheksums match, click Next to proceed with the software upgrade.
A Warning window displays the selected option.
Step 14: Click Install.
The Install Status window displays the Install log.
Step 15: When the installation completes, click Finish
Step 16: Verify the COP file version using this command from the CLI:
admin:show version active
Active Master Version: 8.6.2.xxxxx-xx <-- Note: 8.6.2 is shown for example only; your version may vary
Active Version Installed Software Options:
cmterm-9971.9-0-3ES-1.cop <-- Note: Other COP files such as this may or may not already be present on your system

Call Manager disk cleanup and size reallocation

Version 10 and later CUCM virtual machine ovf has grown from 80 to 110 GB. I have read accounts of the upgrade from 9.1.x to 10.x failing because of a lack of space. This procedure is for virtual CUCM servers.

1. I strongly suggest that you take a storage snapshot before performing this upgrade. You can't take a VMware snapshot because you would then be prohibited from increasing the disk size. It would be greyed out.
2. (UCM 9.1 and earlier only) Install the ciscocm.vmware-disk-size-reallocation-1.0.cop.sgn COP file.
3. Shutdown guest VM
4. Open VMware Infrastructure (VI) Client and connect to VirtualCenter or the ESX host.
5. Right-click the virtual machine.
6. Click Edit Settings.
7. Select Virtual Disk.
8. Increase the size of the disk to 110GB.
9. Power on guest VM.
