What to do

I have RH 9 and I am pretty happy with it. The end of life is
sometime in April and I would like to know if I can change over to
Fedora without losing most of the programs that I have , i.e. O.O. ,
StarOffice and the like.

I have been following this list for quite a while and would like to
know if I have to start from scratch, clean install, or if I can just
switch over to Fedora without too many problems.

TIA.
