To upgrade from 10 to 14 is a bad idea..... You are better off backing up your data, and doing a clean install. Also, you should install either Fedora 15 or 16, as the end of life for Fedora 14 is about to come up (On December 8, 2011).
Edit - I also want to add that if this is indeed a real server, running Fedora, I highly suggest that you switch distros, since Fedora is a rolling release distro. You should a distro that isn't ended every X amount of months, especially since end of life distros do not receive any more updates. This is bad, since you need to be on top of system updates to minimize severe bugs and exploits.
