Windows Small Business Server 2003 R2 Transition Pack
First of all Microsoft offers a Microsoft Windows Small Business Server 2003 R2 Transition Pack. This pack converts Small Business Client Access Licenses to Windows Server and Exchange Server Client Access Licenses, which would mean you could make your transition without having to purchase new licenses. I would contact my Regional Center*to find out if Microsoft has plans to make a Transition Pack available to go from Windows Small Business Server to Windows Server 2008 and Exchange Server 2007. The tool will help you transition technically as well.

When you move mailboxes using the Move Mailbox Wizard from your Windows Small Business Server to Exchange Server 2007 within the same Exchange Organization, you won't need to change the Outlook settings on your clients anyway... This is a Outlook feature.
