You cannot do an in place upgrade, retaining programs and data, from either
x86 XP or x64 XP to x64 Vista. You can, however, use an upgrade edition of
Vista x64 to go from either x86 or x64 XP as the qualifying OS, but you can
only do a clean install.
To use the upgrade product key to install x64 Vista, boot from the Vista DVD
with XP installed, enter the product key, it will check and see a qualifying
OS is installed, then allow you to do a clean (custom install). The XP
installation will be wrapped up into the windows.old folder which can be
deleted. Neither data or programs is migrated to the x64 Vista
