Migrate Exchange 2003 to Exchange 2010

Hello,
I am migrating Exhange 2003 Mailboxes to Exchange 2010..
I am about 50% through this process, with some of the mailboxes having been moved to Exchange 2010, and some of the mailboxes still residing on the Exchange 2003 server.

During this process, do  ALL Exchange users continue to point to the 2003 ExchangeServer?
That is my assumption.

If mailboxes have been moved over from Exchange 2003 to Exchange 2010, then my assumption is that Exhange 2003 will inform the email users whether to point to the "old/legacy" mailbox on the 2003 server, or to point to the "new/User Mailbox" on the 2010 Exchange Server, based on where their email box currently resides.
Thanks

Outlook from inside your network will update itself.

From outside for OWA you need 2 IP addresses and 2 URL's.

Did you want confirmation or do you have a specific problem?

See my guide here, it's for SBS but the process is identical: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html
