[cisco-voip] Fw: Need Advice on CCM and Unity Upgrade steps:

[Justin Steinberg]

I think you have the right idea here.  I'd recommend running this
through in a lab first, or pulling a hard disk from your publisher
before starting.

You will also want to install the latest CallManager service release
for 4.1(3), which I believe is CCM 4.1(3)sr3a.

Also, Unity TSP 8.0(1) is buggy.  You will want to upgrade to a newer
TSP such as Unity 8.1(2) - which is compatible with CCM4.1(3).
