This package lists and summarizes all the SQL changes from version 2.2MS2 to 2.3.3 including some missing SQL statements that were missing in the official upgrade instructions. This allows an easy way to port and existing 2.2MS2 database to a stock OSCommerce version 2.3.3 with all customers data intact. The file also lists all the SQL updates by version. So if you are upgrading from 2.2RC1 to 2.3.3, just ignore and delete all the earlier SQL listed earlier than 2.2RC1 Please see http://forums.oscommerce.com/topic/376743-upgrade-database-22-231/ for more information regarding the upgrade. Limitations: There is a need to create a new admin user data.
