upgrade CUCM 6.1.5(su3) to 8.5.2

Hello,

I was wondering if the CUCM 8.5 is installed on the inactive partition of the CUCM when upgrading from 6.1.5, or if the upgrade is overwriting the CUCM 6.1.5 (like the upgrade to 8.6).

Thanks a lot,

Best regards,

Antoine Meunier

Antoine,

Yes you still have the inactive partition which is your 6.1.5 in this case..

here is the release note

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

Hi Antoine,

Is its a linux to linux upgrade, it doesn't overwrite the active partition. The next version is always installed on the inactive partition, the moment when you perfrom switch version, this new version gets enabled and makes this partition as active partition.

Hope it helps.
