Sooner or later I want to upgrade to a 64 bit kernel and 8 GB of RAM.
Other than this article, I can't find any information on the subject.

I am looking to do the upgrade WITHOUT reinstalling Fedora. I've done
enough re installations in the past to know that I don't want to go
there.
Has anyone done crossgraded from 32 to 64 bit ? What advice do you have
to offer ?
Have you really done enough upgrades? I think not. If you did, you
would know that the best advice is to back up your files and perform a
clean install.
No, that is NOT the best choice. I've re installed clean more than 4x
and its a BIG pain setting things up again. I have a lot of software
installed and not all of it is a simple yum command, ie custom versions
of Eclipse, java, etc.
Just like we shouldn't be telling everyone to do a 'yum clean all' when
its not necessary, nor should we be telling people to reinstall.
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.
Good Luck
