If it is a server environment, you should be paying attention to the supported life of the distribution. FC2 is long, long past its 'use by' date. > Make lists of rpms on the FC2 install, and then sdiff'ing with > the list of rpms installed from the CentOS upgrade should be one way of > identifying non-CentOS packages and/or duplications. Just get the package list from the working C5 box and feed it to kickstart or to yum after a minimal install. > Last, CentOS is built from Fedora Core 6.

You might, with a lot of work and care, make the upgrade operational, but the result will be a one-of-a-kind beast that doesn't belong in a production environment. > But how much difference is there from FC2 to > FC6/CentOS 5.*? The point is that nobody knows, and there's no reason for anyone to know. You weren't supposed to run things that long on Fedora. But if you are going to let things go that long again with no maintenance, I'd recommend jumping all the way to C6 even if it is more work now, so 'yum update' will take care of it for years. -- Les Mikesell lesmikesell at gmail.com
