[cisco-voip] Unity Upgrade and Migration Scenario

[Ed Leatherman]

I've only used COBRAS to migrate to Unity Connection 7, but your plan
sounds reasonable and worth testing. I think it will be much smoother
since your VM-only anyway to have a new server. I just used COBRAS to
migrate users from Unity Connection 1.2 to 7.0 on a new server and it
went very smoothly - much better than DiRT imo. couple things to keep
in mind..

COBRAS doesn't quite migrate everything, make sure you note from the
documents which items are not

>From my limited experience with it, COBRAS can take quite a bit of
time to export messages. for a 900 user unity connection system it
took about 2 hours to export messages off of a 7835-H1.

I agree with Lelio, maybe thing about migrating to connection if your VM-only.
