If in doubt, i always did a fresh install, so never had a messup. 
Conversion? Never ever. Dot.

I am running SL7.9 of FermiLab  now. Im sure RH will continue to share 
updates. There is no spilt milk, why cry?

If needed, i will have a follower OS prepared in good time ready to 
switch to. (Checkouts with VirtualBox since a long time).

Where to go later? Dont think it will be debian then; I read DistroWatch 
now and then

Regards,
Rainer
