1
Main upgraded store ZIP
The reference, e.g. Q2 Industries. Remembered after the first run — you can leave it empty next time.
2
Main store SQL
Its database dump — enables schema comparison.
3
Store ZIP to upgrade
The complete store, uploads and all.
4
Store SQL
That store's own dump.
Installing the result
1. Back up the live store.
2. Unpack the ZIP over it. It is the complete store, so it can also replace the folder outright — but keep that store's own config.ini.
3. Run _upgrade/schema-upgrade.sql against its database. Additive and safe to re-run.
4. Delete _upgrade/ and upgrade-db.php from the server.
5. Rename user.ini to .user.ini; enable the GD extension.
