When releasing a new version, we suggest you to follow the update procedure:
Stop the processes launched by the scheduler from the “Administration” application.
Log out all the users (including yourself)
Backup of databases and old sources
Update sources of old sources
Overwrite the config folder with the one of your old installation
Reloading Apache for the support of the new extension
Log in to the Administration application, edit the configuration, and save it in order that the new variables are supported
In the zone “Databases”, use the button “Repare tables”, the scripts for the update will launch. According to your setup, this operation may take a while.
If you are using a memcached module, flush this cache
(either restart the memcached server, or use the button in the dashboard of the Administration application).
Relaunch the tasks through the task manager
