How to switch from kde 3.5.9 to 4.2 ?

Hi

I have downloaded 4.2 beta, and ran plasma. Looks awesome.
Well, i’d like to make a switch. How do I do it?

I suppose I’d have to make new user so my old kde settings doesn’t get in a way (I have customized some panels which were visible when I ran plasma).

Thanks!

just switching kdm3 to kdm4 dont do the trick. ANy hint?

kde4 doesn’t replace your 3.5 you just have to log out and at the log in screen bottom left in sessions pick kde4

But always like that?
How do I make it default?

Oh, yes… sorry, it always boots last session used.
To make a good switch, or new user or to rename .kde directory so it can make new settings.
