I am migrating user accounts from Exchange Server 2003 (that is also a DC, and the ONLY dc in that forest - i know not best practice) to Exchange 2007 in a different forest. I will be using ADMT to migrate user accounts and move-mailbox on Exchange '07 to move the mailboxes.
1 - Is there a better way to do this? (i know exmerge will not work on Exchange '07)
2 - Can ADMT be installed on Exchange 2003 safely? (its the only DC in that forest so I don't have a lot of options).
