Bulk export data
Create a full export file including attachments by running the mmctl export create – attachments command. See the Mattermost workspace migration documentation for details.
While the job is running, you can check its status by running the mmctl export job show command.
When the export job status is successful:
Identify the name of the completed export file by running the mmctl export list command.
Download the export file to your local machine by running the mmctl export download command.
Note
From Mattermost v6.0, this command has been deprecated in favor of mmctl export commands as the supported way to export data out of Mattermost.
The export command runs in the CLI. It has permissions to access all information in the Mattermost database.
To run the export command:
Navigate to the directory where the Mattermost server is installed. On a default install of Mattermost, the directory is
/opt/mattermost.Run the following command to extract data from all teams on the server. Note that you can change the file name and specify an absolute or relative path to dictate where the file is exported:
sudo -u mattermost bin/mattermost export bulk file.json --all-teamssudo -u mattermost bin/mattermost export bulk /home/user/bulk_data.json --all-teamsRetrieve your file from the location you specified.
At this time, the export supports attributes of the objects listed below. All Mattermost bulk export data files will begin with a Version object as the first line of the file. This indicates the version of the Mattermost bulk import file format with which the exported data is compatible.
You can export the following data types:
Teams
Channels (public, private, and direct)
Users
Users’ team memberships
Users’ channel memberships
Users’ notification preferences
Posts (regular, non-reply messages)
Posts’ replies and threads
Posts’ reactions
Custom emoji
Direct message channels
Direct message posts
Note
Configuration for data types such as exporting specific areas of the server, exporting additional types of posts, permissions schemes, file attachments, webhooks, and bot messages is not yet supported. Deleted objects are also not yet supported.
For requests to add additional attributes or objects to our exporter, please add a feature request on our feature idea forum.
