BES compatibility with Exchange Server

Currently, my Company is running a BES server version 4.0 in an Exchange 2003 environment.  We recently introduced Exchange Server 2007 into the same domain and will be migrating some BES users from Exchange 2003 to 2007.  Upon research, it looks like I will need to upgrade BES to the latest version to integrate with 2007, but I can't seem to find any information on whether or not I can run a single BES server that works with both Exchange 2003 and 2007 as I was not planning to migrate all of my BES users over to 2007 right away.


If anyone has any knowledge or experience with this that they could share, I would be most appreciative.  Thank you!
