As others already determined, the steps in /usr/src/UPDATING are not sufficient for a successful and smooth upgrade. While we upgraded machine after machine this week, we had to adjust and enhance our upgrade procedure many times. Now that all of our machines were successfully upgraded, I want to share our experiences with you by forwarding you our last version of the procedure. I'm sure some steps can be simplified or perhaps even left out, but I did not care very much about optimizations or speedups. For us it was just important that the upgrade worked correctly. And that's the case with the above steps. I hope this procedure can help you a little bit in upgrading your boxes, too. Yours, Ralf S.
