what to download for upgrade...

I would like to upgrade my SuSE Linux to 8.0. Someone mentioned that I can download it from the ftp site. I looked for it but under the ftp://ftp.suse.com/pub/suse/i386/update/8.1 directory I didn't find any big file. Under the ftp://ftp.suse.com/pub/suse/i386/live-eval-8.1/ directory I found a large ISO which I assume is the prime download. But I don't want an evaluation copy of 8.1. If I install it over my 7.0 version, will I not have an eval version? Lehel Kovach
