Looks like the old server doesn't stay up much at all anymore. And since it's kind of difficult currently to get access to the server I just restored everything from the previous night's backups. Latest mailing list subscribes/unsubscribes may need to be done again. Also I think there are some old configurations (and other things) still somewhere.. I'll change these as found and maybe I'll get access to the old server some day soon and can check again what differences there are.
