Ok here is my scenario domain A is and old Win2k3 domain and needs to be moved to Domain B with users mailboxes from Exchange 2003.
I have set up the trusts and can transfer users from one domain to another using Active Directory Migration Tool. What would be the best method to get Exchange over? Is it a case of have a temp server to move the exchange mailboxes to then formatted my current exchange server, rebuilding to Domain B and transfering it from the spate box on Domain A to the new exchange on Domain B. If so could someone that has done this give me some more detail info.
Very much appreciated
