I have an existing forest/domain that runs Exchange 2003. I created a
completely new forest and domain and installed a new Exchange 2007
organization. I am creating a forest trust to migrate the mailboxes from
Exchange 2003 over to Exchange 2007.
I plan to use the ADMT to migrate the user accounts. I have two basic
1.) what is the best way to migrate the Exchange mailboxes
2.) How to I have email forwarded over to mailboxes in the new Exchange
organization once I migrate the mailbox from 2003? In other words, email
will continue to be delivered to the Exchange 2003 organization until I can
get ALL of the mailboxes migrated over to the Exchange 2007 organization.
How do I forward those over to the mailboxes that have been migrated?
