Do you ever need the mySQL code to convert your db to a later version?
Well now it can be done, just provide me with the old db from the backup admin option and I'll return the db converted to 2.3.1 format or if you prefer just the SQL commands you need to run.
This will make it much easier for you to upgrade your shop from RC2A or MS2 to 2.3.1 and retain the history.
