Exchange 2000 to Exchange 2003 migration + cross-forest move

Hi,

I am looking on some information how what the best practices should be when
migrating from an Exchange 2000 server, to a Exchange 2003 server, but also
moving to a new domain at the same time.

Right now, I have 2 domains (in different forests) setup that have a 2 way
trust set up. The primary domain (say DomainA) is running Windows 2003 AD in
native mode, with an Exchange 2003 server running in Exchange native mode as
well.

The second domain (DomainB) is running a Windows 2000 AD, with the Exchange
2000 server there. I would like to move all mailboxes from the Ex2000 server
in DomainB to a brand new Ex2003 server in DomainA.

I've found that I can use the Active Directory Migration Tool (ADMT) to
transfer the accounts from one domain to the other, but I haven't been able
to find out if there is a way to move the mailboxes as well.

FYI, after the migration, I will be getting rid of the second domain.

If anyone can give any tips or point me in the right direction, that would
be great.

TIA.

Hi,

You can use the mailbox migration wizard. This tool is installed as part of
an exchange 2003 install.

Hi,

Ok, so would I use the ADMT first to migrate the accounts, then use the
mailbox migration wizard? Or will the migration wizard move the accounts and
the mailbox?

Hi,

Use the ADMT to migrate the user accounts and then the mailbox migration
wizard to move the mailboxes.
