Just run the FC6 installer.  The installer will find the existing FC4 
partition, and will prompt you to upgrade.  It's pretty much automatic.

Your old configuration will mostly be preserved.  After upgrading, review 
/root/upgrade.log, which will list all configuration files that have been 
updated.  Manually edit them and make any necessary changes.
