In some scenarios, a site may have a newer version of a module installed, while the DNN / Evoq upgrade package might contain an older version. This will be true for Security Analyzer. If you have an older DNN / Evoq and applied the latest SA, and then later to a newer DNN / Evoq with older SA, the upgrade process fails half way.
It completely destroys the side.
We need to log a warning and not upgrade the module if it's older.
