Moving from existing Exchange 2003 server to new Exchange 2003 server, between two domains

Moving from existing Exchange 2003 server to new Exchange 2003 server, between two domains

I last posted on this in mid-November, and we've not had a chance to do
the migration off of the older box onto the newer box yet. We actually
have two domains running within the company. One is 1st.local which
contains the domain controller/terminal server that all of the office
computers authenticate against, and 1st.net, which has the current
Exchange 2003 server (Exchange1) as well as our various application
servers. We've been trying to figure out some way of
consolidating/moving around servers without completely breaking
everything. My boss has recently suggested bringing up the new Exchange
2003 server within 1st.local, call it Exchange1 (exchange1.1st.local
instead of exchange1.1st.net), then start bringing up the Exchange
processes, replicating public folders, rehoming folders, the Recipient
Update Service (per MS KB#822931) and so on, and then actually start
moving mailboxes. But going between domains, even trusted domains, am I
correct in thinking we need to use ExMerge, instead of simply moving
mailboxes from within Exchange System Manager, or would this still be
possible?

Thanks in advance.

If both domains in the same Exchange Organization (i.e. same forest), you
can just move the mailbox using ESM or ADUC. If the 2 domains are in
different Exchange Organizations, you need to use Exchange Migration Wizard.

NOT SUPPORTED METHOD (use on your own risk):
Backup the mailbox store database on that old server and restore/attach the
database to the new server. Delete the users' mailboxes (i.e. unlink the
mailboxes or mailbox-disable the users). Use Mailbox Recovery Center to
reconnect the users to the mailbox clones on the new server.

You are correct, I would suggest using Exmerge to export your mailboxes into
the corresponding domain.
