I have a very tired 32-bit machine which has Windows 7 running on it. This Windows 7 was installed as an upgrade from the original XP installation. Both 32 and 64 bit DVDs were included in the upgrade kit. Is there any way I can install the 64-bit system onto this machine when I replace the 32-bit motherboard with a 64-bit?
 
Do a clean install on the new machine.
When is says that no windows is installed, it will ask you to insert the Windows XP/Vista disk in the CD/DVD drive and check for certain files on the cd.
If you do not have a windows XP or Vista CD/DVD you will need to download and burn it to disk before you start the new install process.
Been there done that before.
I have disks all of the way back to a windows 95 upgrade disk. As an upgrade from windows 3.1.
 
Another option would be to install the old disk in the new computer as extra storage and install the 64bit version on your new hard drive.
That way the installer will find a copy of windows already installed.
Then when windows is installed return it to the old computer reinstall Windows XP and donate it to a local charity/Community thrift store.

Not sure I have an old XP... disk (didn't have your foresight), but will look, and otherwise will try your 2nd suggestion. I would have kept the old disk for data recovery anyway. Only question in my mind is whether w64 will treat itself-32 as a base for the upgrade. I'll let you know what happens.
