And I highly recommend to not do that! The upgrade process is still not 100% smooth and it can be hard for normal users to fix theire systems if they encounter an error while upgrading. So, do not upgrade to 0.6 if you don't really need to.
Sorry I should clarify what I meant. I have never been a big fan of upgrading an OS via dist-upgrade etc and have always opted for a fresh install. What I meant by upgrade was 'move to'. I did a clean install of Wheezy and put Kralizec on it. This is how I would suggest it be done.
