Technically no, you have to start the upgrade from within an existing
installation. However, there is a workaround. You boot with the DVD and
start the installer, and at the point where you insert the Product Key,
simply bypass it and then choose the appropriate version of Vista. Complete
setup, then login and reinsert your DVD, start setup again, this time
inserting the Product Key. Basically, you install twice.
