upgrading fc6 without burning a dvd?
so i know this is probably a stupid question, and i've searched for it, but the long and short of it is i haven't booted this box in about a year and i have just learned that fc6 has since reached the end of the line for updates. i booted this machine because the RAM died in my other one which coincidentally has the dvd burner in it, only now i can't get any updates or other new cool stuff.
now my question is, can i somehow upgrade to say fc9 without having to burn a stupid cd. i feel like i should be able to mount the iso as a ghost drive, but i don't know if that even makes any sense or not. any help would be greatly appreciated
