Joel's given you good advice. It should work, but there's always the
chance that something might go seriously wrong on any OS upgrade.

Apache these days is covered by SELinux: I'd say that there's a very
good chance that you'll need to do some reading and relabelling to get
that working. In your situation, at least to begin with, I'd strongly
recommend turning SELinux OFF just for httpd: see
http://fedora.redhat.com/docs/selinux-faq-fc3/index.html#using-s-c-securitylevel

Squid is simpler, and might Just Work. But that's also covered by
SELinux.

Apart from that, in my experience, text mode user space is very similar:
there's just the known version upgrades. How much customisation /
configuration have you done on any of the daemons you mention?

I'd always advise that you don't pressurise yourself: tell everyone that
downtime might be much longer.

My sigmonster's on the ball...
