Hosted Exchange and 365 coexistence?

Is it possible to migrate only a portion of users from a domain using Exchange 2003, into office 365/Exchange online?
Is there a way to configure domain settings so that email from some users goes to 365 servers, and the rest goes to the existing on site Exchange server?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
