That's fine if it's really a full version. Just be aware that you
can *not* do an upgrade with an OEM version, and many people
confuse the Full version and the OEM version.
If it is a retail (not OEM) copy, and the Product Key has not been used
with a different machine, then that will do it - just run it from the
present system, enter install and continue with Upgrade. Otherwise you
need the Pro Upgrade CD
I would first check on any possible consequences of proprietary hardware
though
