I have been running RedHat 7.3 for a very long time and it has been just wonderful. I am quite happy to stay with this build as all the things I need from linux are working well (internet access via ppp/adsl, firewall, file server to my kids, ip forwarding and masquerading (internet access for the kids), good java programming environment with eclipse and a CVS server over ssh).
However, I am finding that a lot of new things that I would like to try and explore will not install (via rpms) because of the age of libc libc++ etc... For instance, I had to build the jikes compiler from source yesterday because the rpm would not install :-(
So, here is the question. How painfull would it be to ugrade to the latest version of RedHat (I don't even know that the current version is)? It took me a long time to get printers, firewall and adsl to run properly. Would I lose all that and have to redo them?
Also, if I have built jikes on this machine and upgrade to a later linux version, will the jikes binary still work or do I need to recompile it?
Can someone suggest a reasonable migration path?
