Bellow, the USB Product ID is depicted for each case.
NOTE: This is no longer an option starting with Fedora 18 though so you've been warned. New in Fedora 17/18 is a tool called Fed Up (FEDora UPgrader) which purports to do "dist-upgrades" similar to Debian/Ubuntu distros.
Having tried this method on numerous occasions I would not consider this to be on par with the available in the Debian/Ubuntu distros which actually worked very well.
Additionally having maintained RHEL, Fedora & Cent OS systems for over the past decade, I would never even consider using this method for anything. So typically people would do one of the following: Use the Rawhide release, which is the bleeding edge version, similar to how Sid is in Debian.
Rawhide offers rolling releases in the sense that it always has the latest versions of packages, but it's by no means meant to be used as a day to day distro, it's really meant only for testing.
Just live with this fact and stay up to date as long as the distro stayed around, using As a new version comes out, you'd manually do a fresh install and take care to copy any data and configurations forward to the new system. This tool essentially just collected your setups and the names of the packages you installed and would assist you in applying them to a new installation.
