Updating from earlier versions

T.Lion 5.6 and 5.5 introduce a new database structure and internal dependencies. To update from T.Lion 5.4 or earlier versions, prepare a clean Debian 9 server (or several servers for high-availability configuration). Refer to the deployment instructions for details.

Once the new servers are ready, contact TASSTA Support to perform data migration and update to T.Lion 5.6.
All server configuration, including users, channels, rules and settings will be migrated to the new server.

Important:

The migrated data cannot exceed 1.5 GB. While the server configuration always fits this limit, it typically means that only the last month history is transferred to the new environment.
