Are you planning to migrate legacy mailboxes to Exchange Server 2007? You’ll need to prepare
carefully, and you’ll want to take advantage of a new wizard that streamlines the process
Step 1
Before you begin, back up your legacy Exchange servers.
Step 2
Consider upgrading to Microsoft Office Outlook 2007, so users can take
advantage of new features in Exchange 2007 that only work with Outlook
2007.
Step 3
Prepare your Outlook Web Access (OWA) users for possible delays when
migrating large mailboxes that aren’t sorted by the date messages are received.
Step 4
Launch the Move Mailbox wizard from the Exchange Management Console.
Step 5
Use the Move Mailbox wizard to make choices on handling corrupted
messages.
Step 6
Use the Move Schedule feature in the wizard to schedule the move. The wizard
lets you schedule a move during off hours. You can also set the wizard to abort
tasks after a given number of hours.
Step 7
After the move is complete, keep your Exchange Server 2003 servers online
for a few weeks, so you can move mailboxes back to them in the rare instances
where performance or compatibility problems arise.
