fc10 upgrade or migrate? whats easier, better

view story

http://www.linuxquestions.org – I have a fc10 installation with lots of programs and specific configurations. I have tried to update using yum, but it fails because dependencies. Have tried clearall, and other options I found in threads, but still fails. I have spent a lot of time. So the question is is it possible to migrate everything to a recent version or do I really need to find a fix to the update and use yum or preUpgrade? I'll appreciate your help. Carlos (HowTos)
