Upgrade order

Answered Question
Jul 11th, 2007

The TSP matrix (found at http://www.cisco.com/en/US/docs/voice_ip_comm/unity/compatibility/matrix/cutspmtx.html) seems to indicate that, as long as I am using TSP 8.2(1), I can continue to use my existing Call Manager 4.1(3) against Unity 5.0(1).

Our Call Manager is used solely for Unity Integration (no phones), but I think it might make sense to upgrade CM (after upgrading Unity), as we are so far behind the times.

What is the conventional wisdom on this? Should I leave well-enough alone in the Call Manager world and just upgrade Unity, or is there a compelling reason to march forward with the CM upgrade too?

Your advice is greatly appreciated!

Hi Tony -

Are you talking about making the upgrade to CCM 5.X as well? We are running one cluster at version 4.1(3), which is very stable I must say :-) and have no plans to move to CCM 5.X due to our IPCC Express high-availability deployment, which CCM 5.X does not support. However, we have another cluster running CCM 5.0 on Linux. Both clusters are integrated with the same Unity 4.2(1) server and function just fine. We will be upgrading Unity to 5.0 soon. If you need the CCM 5.0 features, or want to go to Linux platform for availability (minimal OS maintenance due to non-Windows platform and easier CCM upgrade options), then consider doing that. But I think you are fine where you are too.

Hi Ginger,

Yes, I was thinking about CCM 5.x, again just on principle - not because I needed features. Some vendors (but not Cisco) will not talk to you unless you are running the latest version of their product.

It sounds like you have the same experience I do with CCM 4.1(3) being very stable. No sense upsetting the apple cart!

I do appreciate your input. I am now leaning toward going to Unity 5 for Exchange 2007 compatibility, and leaving CCM where we are today.

Thanks again!
