[SLE] Suse 9.3 upgrade box

Hi guys, Now 9.3 will be released within a few days, I was wondering if you can buy a Suse 9.3 UPGRADE and make a complete new clean install with it. Is the only difference between Suse upgrade and the full version really only euros and maybe a manual? I've searched for a answer but I didn't manage to find it, so if anybody can help me out... Kind regards, Guus
