Upgrade

The upgrade is like a classical Drupal upgrade procedure.

You will have to follow these main steps:

First of all, make a full backup of your Opigno's directory and database. In case the upgrade fails this could be very useful to go back.
We recommend to always upgrade from the latest previous version, and to avoid jumping to many versions in one time. We also advise to make sure that all Drupal modules external to Opigno core (including Opigno Apps) are up to date, and to upgrade them if necessary. You can usually check the available updates at: http://your-domain.tld/admin/reports/updates
Put your Opigno platform into maintenance mode
Download the last version, unpack the files, and transfer them into your Opigno directory
Connect to your Opigno platform as an admin, go to the URL: http://your-domain.tld/update.php, and follow the different steps
If everything goes well, put your Opigno platform off maintenance
