migrating from sbs2008 to exchange 2010 - issues with migration

We have gone through the steps as outlined by Microsoft to migrate from sbs 2008 to exchange 2010. We have moved all of the mailboxes, and are now ready for the control to be moved to the exchange 2010 box.
The SBS2008 box and the Exchange 2010 box have the SBS box still as the main transport, etc.
we attempted to reroute email to the new server, but even though it says it delivered, no new mail is showing in the maiboxes
Additionally, when the users login to the web client, it redirects them into a loop between the old server and the new server.
Any help you can provide would be greatly appreciated

Two issues there.
The OWA looping - that sounds like you have the same URL configured on both servers, or have the traffic going to the wrong server. As you have moved the mailboxes you should have the HTTPS traffic going to the Exchange 2010 server. The URL should be unique, not the same as the OWA URL on the old server.

On the SMTP transport issue, if you telnet in to the server on port 25, can you send email and see it delivered?

What does message tracking say?
It could be that although you have moved the mailboxes there are still references to the old server somewhere and it isn't routing correctly. It can also be a sign that you have tried to duplicate things a little too much and Exchange is confused.

Have you run the best practises tool from the Exchange toolbox against the platform to see if it flags anything?

Simon.
