[cisco-voip] Unity 5 upgrading from Unity 4

[Jonathan Charles]

The Windows issue is the big one I am going to be running into... most
of the people who want to upgrade is because they want Windows 2000
out of their network (that is why they went to CCM5.1, MPX, etc...)

A few customers have Unity 4.2(1) on Win2k3, which means the upgrade
should be easy, but if they are running Win2K, that means a complete
blow away and start over...

I did one back in July, and it was a nightmare, we ended up abandoning
the old system and recreating everything from scratch...
