Exchange upgrade-move on new server

By simon ·
I have just bought a new server to replace our old Exchange 5.5 server, I plan to upgrade to Exchange 2003 at the same time and wondered which was the best method of moving users mailboxes from one server to the other but keep all messages and email addresses.

I have a windows 2000 server network using a sinlge domain and need to setup the new server with the new one in place (ideally) then move mailboxes from one server to the other (perhaps over night). Is this possible or do I have to take the current server off line and then call the new server the same name and do a restore? As if I had a bad crash on the exchange server.

Any ideas, links and tips very welcome.

Thank you

If the organization name and all other information will remain the same and your Active Directory environment is ready with the Active Directory Connection in place, then I would:

Stand up the New Exchange 2003 server.
Configure the 2003 server (connections, virtual domains, etc.)
Migrate the mailboxes from the 5.5 to the 2003 Exchange server.
Once completed, stand down the Exchange 5.5 server and remove the Active Directory connector.

Unless there is a pressing reason, I wouldn't stand down the Exchange 5.5, as its existence will give you some fall back capability.

I would recommend that you read over the article and associated ones here:
