I did not do this myself, but some have stated that they dump the 
database before upgrading to a new version. Then they bring it in to the 
newer version. You might find information in the archives somewhere. I 
remember the subject being discussed.

Anyway, to downgrade a package to a previous version, run the 
--oldpackage flag to rpm.
Basically, download the older version and dependent programs to a 
directory. Then run the below from a root terminal and in the directory 
  where you have the older rpms.
rpm -Uvh --oldpackage *.rpm

You should then have the previous version installed.
