openSUSE 12.2 beta live kde update

i want to try openSUSE 12.2 beta live kde, but i have a question:
if i install this version, can i update that to final version in future? or i have to download and install using a final version DVD?

12.2 beta ?
Where are you getting this from?

You can update a development release, but I wouldn’t recommend it

Like Caf says: there is no such thing as 12.2 beta, at least not for a while. ATM we’re in the Milestone phase for 12.2, consider it alpha. Theoretically, yes, you could update all the way through to the final release. But your system by then will not be a 12.2 stable install. And the trouble you met by going through the Milestones will be one accompanied by few.
