I am migrating a forest with 3 domains to a single forst/domain. I will have all user accounts moved to the new forest using admt. I will have all Windows 208 DCs and Exchange 2007 servers in new forest. The source forest contains 3 exchange 2007 servers.
I will probably use the move mailbox command to clone mailboxes across. Previously I have used the exchange migration wizard to do exchange 5.5/exchange 200x cross forest migrations and then use the EXPROFRE script to redirect the users to the new exchange servers.
I used to use a trick in that early in my migration project once I had my users across to the new domain I would clone the mailboxes to the new Forest. Then when it came to the time of rehoming the users I just did an incremental move (or only objects older than x days) I then ran the script EXPROFRE.
My question is with the new move mailbox command can I do the following?...
1. clone the mailboxes across instead of move?
2. Incremental move after clone or clone only mail items x days old
3. To redirect the users to the new mailbox do I need to use EXPROFRE or is there some other built in feature now??
