I have upgraded from fc3 to fc4 without any difficulties. First I installed fedora-release-4-2 rpm so that /etc/yum.repos.d was updated with the fc4 repo locations. Then I just run # yum upgrade and that was it. You can root the installer from fc4 CD and choose upgrade system. I don't think you need a "clean" installation of fc3 - that would no make sense. However I have experienced problems caused by implement of python 2.4, so check that none of your programs need python 2.3. To avoid problems with GCC4 you would probably want to install the compat-gcc-32-* packages, which provide the backward compatibility. ----- Original Message ----- From: "Edwin Dicker" <fedora@xxxxxxxxx> To: "'For users of Fedora Core releases'" <fedora-list@xxxxxxxxxx> Subject: RE: To upgrade, or not to upgrade?
