Replacing HTS & CAS Server - Exchange 2007

I currently have an Exchange 2007 Server running on Server 2003 in a virtualized HYPER-V environment. This server is running the Hub/Transport & Client Access roles and while trying to t-shoot an issue with Microsoft support I was told they do not support Server 2003 on any virtual platform. This server was originally running Exchange 2003 and was upgraded rather than replaced with a new server for Exchange 2007. I would like to replace this server with a new VM running Server 2008 R2.

I really want to rebuild the CAS server as the OWA and other CAS related features are really hokey on this box.

Any recommendations on the best process for this? I need to keep downtime of course to a minimum...

This is what I'm looking to do for this environment:

Move the CAS & HTS Roles from the 2003 server to a new 2008 R2 server.

The mailbox server is already running Server 2008. I want to migrate the mailboxes to an independent clustered mailbox solution running server 2008R2

Thanks for the feedback Will...

Any benefit separating the CAS and HT roles?

I personally would keep them on the same server.
- reduce cost for server licensing
- HT is automatically highly available service with 2 or more in a single AD site

Keep them on the same server.
