Stop the services.
Back up everything.
Install new version of Sympa.
First, read the following notes:
If imcompatible changes had been made, these notes may state them and describe measures you can take.
See also “Stopping services”.
Sympa services should be stopped.
HTTP server should be stopped.
If you are running separate FastCGI service, that service should be stopped at least: HTTP server itself may not be stopped.
Mail transfer agent (MTA) is recommended to be stopped. If it was not stopped, incoming messages will be queued into the spools of Sympa and processed when the services will restart.
Note that database service must not be stopped during upgrading process.
It is recommended to back up all configurations and database in advance.
Configurations are saved under following paths.
To back up database, please consult the documentation of database server.
Contrary to expectations, default settings, especially default templates,
are frequently changed on release by release. Backing up files under
$DEFAULTDIR is good idea.
Update all packages you have installed, including Sympa itself. See the documentation of each distribution to know how to update packages.
Install new version of Sympa distribution according to description in “Install Sympa distribution”.
Update dependent modules if necessary according to description in “Install dependent modules”.
# sympa.pl --upgrade
This will upgrade database schema and reload configuration caches (On binary releases, this step will be done automatically).
See also “Starting services”.
Restart services and check if the system will work properly.
