Fair.  I've added some text; lmk if I've missed the mark.

+RANCiD 2.3 to >2.3
+Assuming that no other specifics in the sections below apply to your
+installation or environment, then upgrades should be straight-forward.
+       - review the CHANGES file for anything that may affect you,
+       - backup your current installation,
+       - optionally disable rancid's cron jobs and waiting for running
+         collections to finish.
+       - follow the quick installation instructions in the README, using the
+         same arguments to configure that were used for the previous version
+         (if any), and installing the new directly over the previous.
+       - it may be necessary to merge new .conf files (rancd.conf, lg.conf,
+         rancid.types.conf) with the existing files, which will not have been
+         over-written.
+       - re-enable rancid's cron jobs

I did not comment specifically about files to backup, as I feel that one
could be extra careful by backing-up everything or one could backup only
the files are locally customized (.conf & router.db files).
