Well then here's one.  Fedup works great!  I've used it many times with 
no problems.

Fedup uses the repo configuration from your current Fedora install.  If 
you don't have updates-testing enabled, then use:
fedup --network 21 --product=whatever --enablerepo=updates-testing

Yes, the issue of the upgrade path breaking around release time is a 
very tricky problem to solve.  Either use updates-testing or ignore the 
breakage (if it's not critical).  When the release happens, the updates 
will be released and the packages will be generally available.
