OK, I realize that I'm behind on my personal systems. That being said, I want to migrate from Fedora 13 to Fedora 16 and at the end of it all, drop VMware Server 2.0.2 in favor of the latest KVM and move from Oracle 11gR2 database to PostgreSQL database.. To complicate things more, I'm running Raid-1 on 2 - Hitachi Deskstar 1.5 TB drives with multiple partitions (including /boot).
I've read that you can only migrate a single version when using Anaconda (i.e. Fedora 13 --> Fedora 14 --> Fedora 15 --> Fedora 16), so I can see the a full migration may take about a week. At each stop, what should I verify to determine if the upgrade went OK? Should I stop my Oracle, JBoss and other applications prior to the upgrade?
Is there some pieces of wisdom any of you can give me on this task?
Thanks, Gene Poole

If you use preupgrade (which then uses Anaconda) you can get away with skipping one version, so you could go right from F13 to F15, spend a little time making sure everything's working, then move to F16.

The biggest piece of advice I can give would be to move to EL6 (either RHEL 6 proper or CentOS 6). They will be supported for about six more years and their packages and patches go through much more rigorous testing, making it a much more ideal server platform. EL6 is (very loosely) based on Fedora 12, so the migration should be more or less painless for you, but of course, test on other machines.
As for KVM (+qemu), it is a great hypervisor. The libvirtd tools are not always the most reliable under Fedora, so I don't rely on them (though I do use them). I don't know if you can simply dd out the VMWare storage for each VM and write it to the backing device or file and have it "just work", but on a test system, it should work.
No matter what you do, mock it up on non-critical systems and dry-run it however many times is needed to get it right. You're talking about very fundamental and simultaneous changes... This will take time to get right.

Although you can migrate, best Fedora practice is to backup what's important and reinstall
