I've done many upgrades of various degrees and had precious few
problems.  The most common problem I've had on about half of the
machines I've upgraded to FC2 and beyond from prior versions, is the
need to add "acpi=off" to the boot line.  One of my clients has two
very similar Athlon-based servers.  One requires it; one doesn't.  In
FC3, if it fails to boot without it, a message will tell you to try
it.

The only specific gotcha to watch for is, on several recent FC2-to-FC3
Postfix' /etc/postfix/aliases has been abandoned in favor of the more
conventional /etc/aliases.  Just change the applicable entries in
/etc/postfix/main.cf, and you're up.
