Default [Q] Upgrade from v2.0 and GT-I9100 to 2.9 wizzedkat

Hi everyone, Hope this is correct way to post my question.
I need help advice about upgrading my Samsung S2 GT-I9100 to 2.9 wizzedkat rom from
build number WizzedKAT 2.0-rrgrrg-S%-edition. WizzedKAT ROM V2.2 as per photo.
Can I download the full rom.
Then Do a full wipe, wipe dalvek cache, wipe cache, then install zip rom, then reboot.
or which is the correct way to do it. I love this rom no major probs with it at all.
Still a novice be gentle, have looked thru forum but nobody going from 2.0 to 2.9. to get info from.
Thanks in advance.
