Honestly unless you are very experienced with 64 Bit systems, then I
would suggest a clean install.
If you really won't consider this then I would suggest that you free up
some hard drive space so that you can create a new partition. Then do
a minimal 64 Bit install to this partition almost like you wanted a Dual
Boot setup. Then you can work through migrating your data or work out a
way to use the data in place.
I haven't specifically does this with Fedora, but I have with CentOS.
If you compile your own software I strongly suggest you experiment with
this to ensure that 64 Bit libraries are found when you expect them to
be rather than the system finding 32 Bit Libraries First.
