Probably.  However, while SuSE has always been buggy, Ubuntu isn't that much
better AFAICT.  You've heard all the "OMG Unity is horrible!!1!" traffic on
various mailing lists, right?  That's more important for orkstations than
servers, but it shows they're out of touch with users' wants.  I'd go for
CentOS or Gentoo myself.

Yes.

That should work.  The main thing you'll have to do is account for all the
differences between the old distro and the new distro in terms of running
programs and config file differences.
