Server Update

\"RedHatI have one place where I want to update RedHat Linux 9 to something newer like Fedora Core N and at this point I am full of fear :(

Currently the server is handling:

And the mystery for me are the next set of question:

  • To which release of Fedora to update?
  • How to update (cd update/cd clean install/apt-get distr-upgrage/anything else)?
  • Should I leave the same soft or should I replace something (like Exim -> Postfix, IMAPd -> Cyrus IMAP)?
  • What problems may occur?
  • How much time the whole process can take?
  • How to make it with minimum downtime?

In addition – I have space (but a bit old) P3 machine which I can use in any way during the setup.
So what – any ideas???

I thought of moving as much as possible to the P3 machine (web,ftp,mail,samba,mysql), then reinstalling (fresh install) the main server, then move everything back from P3 machine, but I assume that someone may have some better ideas :)
