Upgrading KDE to 4.4x on 11.2?

I just installed 11.2 on another machine and was wondering if it is wise to upgrade KDE from 4.35 to 4.4xx - are/did any people have problems with this?

(and to do this, do I just enable factory repos?)

Add the factory repo, refresh it, then follow: ImageBam - Fast, Free Image Hosting and Photo Sharing

Mind, do not add the Factory repo, but the KDE4:Factory Desktop repo.

ah, got it - thanks a lot!
