[cisco-voip] CUCM6.1.4 Upgrade to 8.6.X on New Hardware

[Joe Martini]

A few things to point out.  Installing or using any non 8.0.3 CUCM version on VMware is unsupported.  I've personally seen issues with the license manager service when putting a pre 8.0.3 CUCM version on VMware as you're looking to do, even after upgrading it to 8.x!  The supported method requires an upgrade on the current MCS server to an 8.0.3 or later version, backup, restore to a VM running the same exact version.  That's why we created bridged upgrades, so that you can install 8.x on hardware that doesn't support it, simply to take a backup to move to VMware.  

Adding to Abebe's reply, also remember that any custom TFTP files or MoH files will be lost using the rebuild method for the subscribers and letting them replicate.  Remember to put back MoH files on the subscribers and custom TFTP files, and even certificate loaded on the OS admin page for secure LDAP connections, etc.

Again, I'd highly recommend not using the 6.x on VMware method.

Hi guys,

   I need to Upgrade PUB + ONe SUB from 6.1.4 to 8.6.X on new MCS Hardware.

 

Customer want upgrade without modification on the actual Cluster, so I can't upgrade in place the cucm 6.1.4.

 

 

So using VMware infrastructure i made an exact copy of the 6.1.4 customer cluster.

 

Using Disaster Recovery export all PUB configuration from the Production Cluster and imported on the VMware copy.

 

Afeter that I'll proceed with the upgrade step 6.1.4 -> 7.1.5.33900-10 -> RefreshUpgrade -> 8.6.1.2000-1 on the Virtualized environment

 

After that Using again DisasterRecovery export DB of the virtualized PUB and the Import again in the MCS Hardware PUB.

 

Question for you!

 

Need to make the same for the SUB, or is possible to install the SUB directly on the MCS Hardware without all the upgrade step ?

 

Thank you very much

 

Regards

 

Alessandro Bertacco
