SL6 to F16??

[Beartooth]

	I've been playing with Scientific Linux on an oldish machine, and 
now I want to try F16 with xfce -- *not* live, but installed, with 
the .iso on a DVD. I realize that requires me to install the gnome 
version and then add xfce. Do I just command "yum install xfce," or is 
there something more esoteric?

	In the course of playing with SL, I've put spare copies of 
various data into it, and of course tweaked all sorts of things, many of 
them a tad bit tedious; I'd like to preserve them into the F16 install. 

	Is there a way Fedora can treat SL6 as if I were upgrading 
earlier Fedora install? I see this : 

$ uname -a
Linux Hbsk.localdomain 2.6.32-131.17.1.el6.i686 #1 SMP Wed Oct 5 17:20:08 
CDT 2011 i686 i686 i386 GNU/Linux

	There's plenty of space for dual-booting. I suppose I could 
install into free space, boot to it, mount the SL partition, and copy 
stuff. But that sounds like needless hassle to me, even if I got all  of 
it right.

	Is there another way??

I have precious (very precious!) little idea where up is.
