The general procedure to upgrade to a new release:
An upgrade process will run when logging in as admin after upgrading the cart files. During this process, the previous database is backed up into ttg-be/data/cart/database_backups, and any changes to the database are applied.
The upgrade process may sometimes include more files and directories than those listed above. We will endeavour to detail these at the time of release.
Should you encounter any issues in upgrading, please visit the CE3 Cart Forum, at http://community.theturninggate.net/forum/34/ce4-publisher/
