I have an exch2007 server In domain A. I have a second exch 2007 in domain B (separate Forests trust in place). Can I migrate/move mailboxes from domain A to the exch2007 server in domain B? Then assign domain B permissions to the migrated mailbox?
Do I need to run active directory migration tools and migrate the users in Domain As sids to domain B? or can I just migrate across the 2 forests etc?
