Does XP need to be de-authorised to move to a new Mac?

[bilbo--baggins]

I've got Windows XP Professional that came with Office 2004 (found instructions to make an installation CD online, and the key works fine). I gather it's not an OEM licence and can be moved between machines.

Is there somewhere in Windows that I need to go to 'de-authorise' XP on my MacBook before I install it on my Mac Pro?

No - If it is a retail copy, you have to call Microsoft and tell them you are moving it - they will activate it over phone.

So just delete the original OS copy and install on the new machine - try to activate - it might fail and give you option for calling along with the number.
