My co-workers and I have been looking all over for a solution to our problem to no avail.
We are migrating our office from one AD to another. That's easy enough using ADMT. The snag we've run into in the planning stages is how do we migrate the exchange 2003 server and the relevant info at the same time.
I plan on migrating the AD user IDs with the keep SID option. All the documentation I have found on the web so far describes how to migrate from Exchange 5.5 to 2003, but nothing explains how to do a 2003 to 2003 migration.
At the moment we plan on just moving the exchange server from Domain A to Domain B.
