I appreciate your and others' efforts at advice. I'm simply trying to use existing hardware (that's the eco-friendly approach), and trying to build my understanding of the Fedora/CentOS operational relationships. Given that it has been stated that CentOS 5.x was built from FC6, and that someone had already offered general guidance on the upgrade procedure (I shared the link in my initial request), I thought that it would be worthwhile asking the CentOS-users list to see if someone from this community had any direct experience with the upgrade. I'm not yet looking for a recommendation for a clean install.
The issue here is that upgrading between major versions (CentOS 4.x to 5.x) is not supported or recommended. And if it is not recommended to upgrade from CentOS 4 to CentOS 5, it is even less recommended to try an upgrade from Fedora Core 2 to CentOS 5.
As has been mentioned before, the results of the upgrade will be a box that claims to be CentOS, but has lots of extraneous packages and files left behind from the previous Fedora install. This will result in a system that seems to run fine, but is likely to have strange problems from time to time when something tries to use one of these old files.
