moving mailbox's from exchange 2003 to 2007 cross connectivity?

Dear All
   i have recently set up an exchange 2007 64 bit server , after a few initial install problems it seemed to install ok and pick up the mailbox entries etc from the old server. if i move a mailbox to the new server it no longer accepts mail from the 2003 server or external mail and yet the mailbox's moved to 2007 will talk to each other.   i tried moving just a couple of box's to make sure everything worked ok (email can not go offline for more than a few minutes in our organisation) what am i doing wrong? do i need to migrate them all across and will i loose external connectivity?. the domain i have installed exchange 2007 in is part of a forest , will this effect connectivity to other donmains in the forest.
 help greatly appreciated

When you setup 2007 and new routing group connector is create between the 2003 and 2007 which handles mail flow between the 2.

Common issue that have caused problems:
Try disabling AV on the 2003
Verify your smtp virtual is not forwarding to a smart host
