Advice from experts required:
I have an Exchange 5.5 server in a winnt4 domain named OLD. I have
setup a win2k AD domain named NEW with an exchange 2k cluster. I need
to migrate the mailboxes from OLD to NEW, on a mailbox-by-mailbox
basis. Thus, it would be IDEAL if the exchange2k cluster could be part
of the OLD domain and OLD exchange site, while also being part of the
NEW domain. However, we all know that a server cannot be part of two
domains. Any other suggested strategies?
The reason the migration MUST take place on a mailbox-by-mailbox basis
is because the Exchange 5.5 server currently hosts mailboxs for
offices that are scattered worldwide. An all-in-one migration is not
acceptable. Also, we cannot upgrade the OLD domain to win2k. We MUST
create a new win2k domain for various legacy reasons.
I greatly appreciate all responses! Thank you!
