Unified Communications Upgrade Questions

ceverett1

Hello,

We are in the process of planning to upgrade the following to 10.5

Call Manager - 8.6 (Pub, Sub1, Sub2)

Contact Center - 8.5

Emergency Responder - 8.6 (Pub, Sub)

Unity - 8.6 (Pub, Sub)

Presence - 8.6

I have found an enormous amount of information on how to upgrade each individual component, but it seems like little is mentioned on combined components. In the CER documentation it did mention to upgrade CER before the call manager.

What order should these items be upgraded?

If just upgrading, should we use the PCD tool or just stick with CLI or web interface?

Last, licensing, will we have to create a new VM for the PLM? Then we can start migrating licenses (or applying for new ones)?

Thank you,

Chad

CUC is always a wildcard, you can do that one at any point in time.

You want to upgrade CER in advance as the docs mention, and then you want to do CUCM/UCCX as it doesn't seem UCCX 10.5 can work with CUCM 8.6

http://docwiki.cisco.com/wiki/Unified_CCX_Software_Compatibility_Matrix_for_10.5(1)

and then finally CUPS to IM&P upgrade.

Either option is OK for the upgrade, I usually use PCD for migrations, unless it's already installed and ready to be used.

PLM will be co-res installed on every single CUCM and CUC you install, you can use any of those, if you want a standalone PLM, then yes, you'll need to do that install.
