[cisco-voip] Unity migration from 4.x to 5.0

[Jonathan Charles]

I have done about a dozen Unity 4.x to 5.0(1) upgrades...

Here's what I have done.

Install new server with Windows 2003, using Cisco's platform DVD for
Unity (or CUC), install Unity 4.2 (and all accouterments) and then
restore DRT backup, and upgrade to 5.0...

I have had pretty good success... Just note, you may run into a bug
where the Unity 5 install says the server had been renamed using an
unsupported method... if so, go into SQL, check the table,
UnitySetupParameters and look the @PrimaryServer, change this to match
the hostname of the server.
