Have a small customer with Unity 4.0(3)partnered to exch2003. They have moved all users to Exch2007, leaving the Exch2003 server partnered to Unity.
I will be upgrading Unity to 5 and then changing msg partner to the exch2007 box.
When I run the AD schema for the upgrade do I run it on the Exch2003 and/or the Exch2007?
Can I run it prior to doing the upgrade or will it cause problem?
Also, regarding the change to exch2007, how do you actually run this Ex2K7_script?
