These are my personal views and based on my experience. This is one of those situations were "YMMV" (your milage may vary) applies.
The safest way of doing what you want to do is to make a complete backup of all your data, then completely format and reinstall the latest Fedora you want to use onto that system, then copy back your data, and recompile and reinstall all your software.
Not sure how much you know about Linux, but if you have weird / exotic server hardware, you can REALLY put yourself in a world of hurt by upgrading. I used to work with a system that was custom-designed for Fire & Emergency dispatch, and it had some custom device drivers that ONLY worked in Fedora 8, and not in newer versions / newer kernels. I.e I'd have been up a creek with no paddle, or even a boat, if I had gone and did what I say you might want to do above. You need to be SURE your available device drivers will work with a much newer (several versions newer) kernel. This is not necessarily always the case.
I've seen many posts of people who tried to "upgrade" like you mention, and I've yet to see such a process go well and either not
A - fail entirely
B- succeed partially, leaving some things in a non-working state like no networking, no X-windows, problems with chipset support and DMA, etc.
What is your compelling reason for updating?? Why do you want to use the newer Fedora Core versions?
In general, if you have something that works, why upgrade it?
The old "if it ain't broke, don't fix it" school of thought applies.
