Most software doesn't look back and only adjusts runtime files to the
new version you run. Not limited to config files and settings, it can
also be a migration to a new storage/database format. Same for RPM
packages. If at all, they contain triggers/scriptlets that move forward.
Downgrades of such packages would be a completely unplanned and
unhandled scenario.
