FC5 => F8 upgrade : advice?

[Beartooth]

	I've come into possession of an otherwise nice machine (so I'm 
told; I don't speak hardware) that still has Fedora Core 5 installed. I 
want to upgrade it to F8 now, and F10 once that's released.

	Is there a best way to go about it, short of a fresh install of 
F8? It has a lot of data, as well as a lot of configuration, that I'd 
hate to lose.

	Any gotchas to watch out for?

	If, say, I upgrade first to F7 (because I know where my DVD for 
that is), and then to F8 -- do I want to update F7 as best I can in 
between? Or just go straight to F8?
