Our modules will update as they easily detect hooks and missing and changes and necessary database upgrade.
To update the module :
- send the last version using module upload menu in the back-office without uninstalling the older version
- next check that any update has to be confirmed in the module configuration
- delete the cache if you’re on Prestashop 1.4 or earlier
- delete the file / cache / class_index.php on Prestashop 1.5 or higher
