Unity 4.0(3) on Windows 2000, UM.
I intend to upgrade my partner server from Exchange 2000 to Exchange 2003, and the partner server's OS from Windows 2000 to Windows 2003.
As I understand things, from Unity's perspective I merely need to install the Exchange 2003 Administrative Tools, replacing the Exchange 2000 tools, on the Unity server.
My questions are:
May I do the tools upgrade a couple of weeks in advance? I am able to successfully administer Exchange 2000 servers with the Exchange 2003 tools, can Unity behave that way as well? My goal is to minimize the amount of work to be done on the day of the upgrade.
In a couple of weeks we will be updating the AD forest functional level to Windows 2003 -- will this have any effect on Unity?
I do understand that this version of Unity itself needs to remain on Windows 2000.
