Mattermost doesn't show imported messages

Troubleshooting Command Line Interface
1

We migrated our Mattermost team according to Mattermost workspace migration — Mattermost documentation from the cloud to our self-hosted server.

The process worked finde, the process migrated all channels and all users. But Mattermost doesn’t show any messages – although they are part of the import JSON file. Every channel is empty and shows “This is the start of the … channel, created on July 07, 2023.”

As we seached for hours to find a solution, we would be grateful for any suggestion!

Hi Florian,

I’m sorry to hear that you’re experiencing issues after migrating your Mattermost team to a self-hosted server. Let’s try to troubleshoot the problem and find a solution. Here are a few suggestions:

  1. Check Import Process: Double-check the import process to ensure that it completed successfully without any errors or warnings. Make sure that the JSON file used for the import contains the messages you expect to see.
  2. Verify Database: Confirm that the database used by the self-hosted Mattermost server is correctly set up and accessible. Ensure that the necessary tables and data have been imported properly from the cloud to the self-hosted database.
  3. Review Mattermost Logs: Check the Mattermost server logs for any errors or warnings related to the import process or message retrieval. Look for any indications of issues that might help identify the cause of the missing messages.
  4. Check User Permissions: Verify that the users who are attempting to view the messages have the necessary permissions to access the channels and view the messages. Ensure that the users are members of the correct teams and channels with appropriate roles and permissions.
  5. Restart Mattermost Server: Try restarting the Mattermost server to see if it resolves the issue. Sometimes, a server restart can help refresh the system and resolve any temporary glitches.
  6. Reach Out to Mattermost Support: If the issue persists, consider reaching out to the Mattermost support team for further assistance. They can help you investigate the issue more deeply and provide guidance on how to resolve it.

When contacting the support team, it might be helpful to provide them with any relevant details, such as error messages, logs, and specific steps you followed during the migration process. This information will assist them in understanding the problem better and providing more targeted support.

I hope these suggestions help you resolve the issue and retrieve the missing messages.

Best regards,
