Was wondering what you guys think.
My scenario is: Unity 4.0(5) UM with Exchange 2003. 2000 Users. Want to upgrade to Unity 5 while
Upgrading Hardware to. I want to also then point Unity 5 to the new Exchange 2007 cluster already
running on the Domain.
So this is the 2 options I think I have.
1) RunSchema updates for Unity 5
Upgrade current 4.X Server to 5.x
DiRT Backup Unity
Build new hardware into Domain and install Unity 5 (new name and IP)
Switch off old server and DiRT restore on new one.
Point new server to Exchange 2007 cluster.
2) Install Unity 5 on new Hardware with new name and IP
Point it to Exchange 2007 cluster.
Use COBRAS to export Subscribers of Unity 4 server
Import them on Unity 5 server.
Switch of old Unity 4 server
