I am working on upgrading my CUCM infrastructure from 4.1.3 to 7.1.3. I have quite a few users using Cisco VTA 2.1.1 and IP Communicator 2.1.3. I would like to find out if Cisco VTA 2.1.1 and IP Communicator 2.1.3 will work with CUCM 7.1.3 or do I have to upgrade Cisco VTA and IP Communicator at the same time I am upgrading CUCM ? My plan is to upgrade CUCM first then slowly upgrade Cisco VTA and IP Communicator and would like to make sure the existing version of VTA and IP Communicator is compatible with CUCM 7.1.3.
Thanks in advance !!!!
That's correct - I use CIPC a lot in my lab and switch between versions of CCM very regularly (from 4 thru 8). I never upgrade or downgrade CIPC unless I'm rebuilding a PC, and it always works so far...
