Hi,
Technically, you'd need a full version unless you are planning on
reinstalling XP first. The upgrade version has to be started from within an
existing, qualifying OS installation. The upgrade license subsumes the
existing OS license (in essence, XP's license for use becomes part of
Vista's license for use). The manner in which an upgrade qualifies for
installation has also changed as no longer can you simply insert a shiny
disk as proof of ownership during setup.
