I have a client that is setting up a new Exchange 2010 server in a new
Active Directory Forest. He currently has an exchange 2007 server in a
different forest. He will keep his e-mail domain the same -e.g. acme.com
and user mailbox addresses the same -e.g. XXXX@XXXXX.COM .
He wants to have both servers up simultaneously, then migrate his mail boxes
(Some of which are rather large), one by one from the 2007 server to the
2010 server and have the 2007 server forward email for unresolved recipients
to the 2010 server until all mailboxes have been moved. I know how to do
this if both servers are in the same Forest, but that is out of the question
because he wants a new clean forest. So we are definitely not migrating ad
accounts, it has to be a new domain- client does not want to migrate,
insists on a new AD structure since it is already set up for other purposes.
So while XXXX@XXXXX.COM might get their e-mail on the 2007 server,
XXXX@XXXXX.COM will be getting his e-mail on the exchange 2010 server.
I'm worried that if we reboot the exchange server, the outlook client will
try to autoconfigure to the other server, is there a way to disable outlook
from auto reconfiguring to the other server for RPC?
If anyone has found a way to tackle this, your input would be greatly
appreciated. I have only a couple of weeks to get the resolved, he wants to
do the migration complete in 2 weeks, we want time to do testing on it
before it goes into production..
Once all the mailboxes are done migrating to the exchange 2010 server, we
will change the MX record to point to the new 2010 server and turn off the
old Exchange 2007 server.
