Yes, that is exactly, what I wanted to know: does it overwrite all installed packages with packages with higher version numbers ?

I think my original question was wrong told: It is not a matter of the difference between upgrade and dist-upgrade (this difference i well known by me), my question aimed more to like "Hey, if there are higher versions in experimental, are they automatically installed, when doing apt-get dist-upgrade (like it behave, if I am running testing and add the repository of sid in sources.list) ? Or are all versions in experimental ignored, as experimental is handled in a special way ?" ...similar to that, you know what I mean. And yes, Jochen, I know the matter of dist-upgrade, and I always say: upgrade is normal, but dist-upgrade is the "intelligent" upgrade (as you heve to think, before confirming)!
