Probably a good question for fedora-list at redhat.com, however:
1. Do you know about preupgrade ?
It pre-downloads all the metadata, rpms, boot images etc while you 
continue to use Fedora, then when you are ready, you reboot into the 
installer, confirm installation and before too long, you have F10 going.
And is one of the supported upgrade methods (the other being upgrade via 
the dvd disk itself).

2. The Fedora wiki covers inplace live upgrades, and has some hints and 
tips:
