Announcement – Messenger migration to the Matrix protocol (27 April 2026)

We are migrating the GroupAlarm Messenger to the Matrix protocol. This modernisation significantly improves the security and interoperability of our communications. The migration requires a maintenance window and a clean break in the system architecture.

Important information regarding data protection and migration

Encryption & message history: Due to the introduction of new end-to-end encryption, it is technically impossible to carry over the old chat history. Existing messages will therefore be deleted on the cut-off date. Organisations & rooms: We will automatically recreate all existing rooms within your organisations, including the users. Manual recreation of the room structure is not required.

Action required for administrators and users

To continue using the Messenger after the migration, the following steps must be carried out:

  1. App update: Install the new version of the GroupAlarm app on the migration date. The previous Messenger functions will be deactivated upon migration and will no longer be available in the old app.
  2. Manual update of flows: As Messenger links in automated flows cannot be migrated automatically, manual intervention is required: After the migration, navigate to your existing flows. Select the newly created rooms in the respective Messenger actions. Save the flow again to reactivate the function.
