I don't know what you mean by "Upgrade first and have the option of a full
clean install."

If you are running XP Home you can do an upgrade to Vista Home Premium.

If you are running XP Pro the upgrade option will be disabled and you will
have to do a custom install for VHP.

There is no "clean" option in Vista Setup. There is only "upgrade" and
"custom."

If you want to do a clean installation of VHP you need to boot with the dvd
and use the Advanced Options to format the drive.

The custom install option within Setup does not reformat a volume. It will
only do a quick format if the volume has not been formatted previously with
NTFS.
