You really *should* back everything up and do a fresh install of Fedora
(or CentOS 5.5), then re-install your extra packages.  You really don't
want to upgrade in place, unless you really, really, know what you are
doing and/or are willing to live with various (subtle) problems caused
by possibly incompatible 'leftover' packages.

Hint: Having a separate file system for /home is a *good* thing.  Having
/usr/local on a separate file system also is gravey on the side... (for
web servers /var/www, for mail servers /var/spool/mail, etc.).
