Hello,
This doesn't sound like a VMware-specific question. Rather, it sounds like a Microsoft Windows question. Just ensure that the hosts on which the 2008 VM runs can see the same RDMs and follow this procedure to remove the dynamic disks from the 2003 VM and add them to the 2008 VM.

All the best,
Mike
