The only limitation I know of with respect to server versions of the operating systems is not a limitation of Ghost or of the server editions of the OS, but a consequence of either what people put on them - i.e., complex distributed databases with elaborate authentication systems - or run them on - exotic RAID controllers with drivers made of unobtainium.

Doing a simple drive transplant on a server should be fine. You might run into trouble if the drive is on a RAID controller, in which case you'll need either suitable drivers for DOS, or to use Ghost32 on Windows PE to load the specific mass storage drivers for the RAID controller.
