Deactivation is not required - simply uninstall/format the PC.
You may have to activate the new machine over the phone.
If you're lucky you may not even need to reinstall (it's worth a go!) - try
cloning the old drive to the new with a third-party partition manager, and
booting from that - windows will install (hopefully!) the drivers required,
and the complain about needing to activate. If it works, great, if it
doesn't, all you've lost is time :)
