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

[Jason Aarons (AM)]

I think this is a Urban legend.

I've asked my Cisco SE about this and he can't find it documented.  Sort of a hidden easter egg only the TAC engineer can find (using WebEx while you watch?) to tell you that you can't call Cisco TAC any more your on the blacklist?

I would double check this with Cisco but we where told that if at any time a CUCM 6 was built on a VM system even if only used as a bridging build the DB would be marked at unsupported and would remain so no matter what upgrades where done in future,

Hi Joe, my intention  is to install 6.0 without license in VMware environment and after upgrade to 6.1.4, only for import the actual DB of my customer (In version 6.1.4).
After that i will upgrade from 6.1.4 to 8.6 the VMware copy, and the I will export DB in 8.6 version

After, I will install a fresh copy of CUCM8.6 on MCS supported Hardware and import the Exported DB from 8.6 VMware environment.

Only after that i will put the license file on the MCS Supported server in 8.6.X version!

What do you think about that?

I use the VMware copy only for Bridge Upgrade.

I understood the consideration for the SUB about TFTP, I'll need to upload again audio files and Firmware phone files.

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.

you can install the subscriber directly on new hardware it will replicated the DB from the publisher.

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
