I have a couple of Perl scripts to automate the listing and re-loading
of rpms. they essentially automate what you're doing.

If its not too late, here's a suggestion. Put / and boot in their own
partitions, then put /home, /usr/local, and so on in their own
partitions. Then, when you're faced with a new release, you can leave
these partitions untouched, and merely install the new release. There
are any number of administrative details with the new release, but at
least their are details over which you have control, as opposed to
those resulting from an upgrade that didn't quite work :-).

Use yum, but read the instructions on upgrading using yum *carefully*
first.
