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. -- Bowie
