When you run servers that happen to run on Redhat’s open source versions (called Fedora), you’ll get thrown into the dark ages at the rates that they release version numbers. Fortunately there’s a way to upgrade through the versions as long as you have the time and a console connection.
To upgrade from Fedora 7 to Fedora 8, just follow this tutorial. Similarly, follow this tutorial to upgrade from Fedora 8 to Fedora 9.
It’s pretty much the same upgrade procedures, where you use yum to check and make sure that all of the upgrade files are going without crashing dependencies. If there are dependencies, then you would use yum to install those first, then run the upgrades again. And I can guarantee that these procedures work even though it takes a bit of time. I remotely upgraded a server at work from Fedora 6 all the way to Fedora 9 (current version) going through this process. And it runs just dandy right now on FC9. yum.
