[cisco-voip] Multiple Version of CUCM integrated with CER

[Heim, Dennis]

Been down this design before… each CER Group/cluster can support 1 version of CUCM. So technically from a support perspective, you would need 2. Maybe you can get some temp licenses from Cisco? The issue is our good friend JCRAPI.. I mean JTAPI.

Support or work with?  It works, but you may not get support if it doesn’t.

Subject: [cisco-voip] Multiple Version of CUCM integrated with CER

We are doing a parallel migration of several CUCM clusters. The current production CUCM cluster is 8.5 and is integrated with CER 10.5. We need to support the user migration to 2 new CUCM 10.5 clusters. So the requirement would be for CER 10.5. to support (1) CUCM 8.5 and (2) CUCM 10.5 clusters.

We see only one CUCM Version selection option in CER. Does CER support Multiple CUCM versions simultaneously?

Thanks!
