To upgrade, or not to upgrade? Fc3 to FC4

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.
