[cisco-voip] Unity 5 upgrading from Unity 4

[Jonathan Charles]

Has anyone done it successfully?

I have a LOT of customers on Unity 4.X running Windows 2000 who want
to upgrade to Unity 5 and Windows 2003. However, my first attempt was
a complete disaster (ended up having to install from scratch).

Here is the problem:

You CANNOT upgrade a Windows 2000 box to Windows 2003 once Unity is
installed (says so in the upgrade documentation).

So, you must do a DRT backup, install Windows 2003 clean, install your
old version of Unity 4.X and restore it. Then you can upgrade to 5

This is not even slightly as simple as it sounds and has a remarkably
high failure rate.

(we got an error that the hostname didn't match and the upgrade to unity failed)

TAC refused to support the upgrade (this was early July, it had come
off of NPH that day).

If anyone has, I am curious as to what tricks you did to make it work...
