Have an exisitng Exchange 2000 Server (which is running on Small Business Server 2000) and want to move the mailboxes to a new Exchange 2003 Server (running Small Business Server 2003). What is the best way to copy the mailboxes from the old server to the new one? I intend to setup the new Server with the same name as the old one, then disconnect the old one. That means, I assume, that I'll need to somehow export/import the mailboxes. Never done this - so if I'm taking the wrong approach, feel free to tell me!
