Moving mailboxes from Microsoft Exchange Server 2003 Service Pack 2 (SP2) or later to Exchange Server 2010? Consider the following:
- The move process is performed offline, and end-users won't be
able to access their mailboxes during the move.
- Perform the move from a server running Exchange 2010 by using
the move request cmdlets in the Exchange Management Shell. You
can't use Exchange System Manager on an Exchange 2003 server to
move the mailboxes.
- You can't move mailboxes from Exchange 2003 Service
Pack 1 (SP1) or earlier.
- Exchange 2003 doesn't have resource mailboxes. Instead, you
must use shared mailboxes to represent resources. If you move a
shared mailbox from Exchange 2003 to Exchange 2010, the move
request creates the mailbox as a shared Exchange 2010 mailbox.
After you move the mailbox to Exchange 2010, you can convert it to
a resource mailbox. For more information, see Convert a
