Migrating from Mattermost#

Introduction#

Note

The EUDAT Mattermost service has been decommissioned on October 1, 2026. Successor service is EUDAT Matrix.

EUDAT Mattermost is the legacy chat service for the EUDAT members.

Discontinued service page: https://chat.eudat.eu

Migrating to EUDAT Matrix#

Existing content (messages, files, teams, channels) have NOT been migrated to the new Matrix service.

To prepare for the decommissioning, we recommend completing the following steps:

  1. Back up your data. Currently there is no bulk export; messages and files must be saved manually (e.g. copy important messages, download files individually). If you need an automated export for your team, please contact us.
  2. Notify your team. Teams and channels will not be automatically recreated on Matrix.
  3. Set up your team on Matrix. Create a Space (or rooms) for your team on the EUDAT Matrix server and invite your colleagues.
  4. Update links and integrations. If any of your tools, webhooks, or documentation reference https://chat.eudat.eu, update them before the decommissioning date.
