**Summary**

Multiple issues with users and channels when migrating from omnibus to docker, following the official guide.

**Steps to reproduce**

Follow migration guide on [GitHub - mattermost/mattermost-omnibus: A simple way to install Mattermost.](https://github.com/mattermost/mattermost-omnibus?tab=readme-ov-file) until step 4) Restore data

**Expected behavior**

Logging into the instance, I would expect all users and channels to exist.

**Observed behavior**  
First when restoring the database there are multiple issues, that e.g. indexes are already existent. I ignore these and assume them expected.  
Issue 1) When I log in, no users exist.

I drop the whole mattermost database in postgres and then `pg_restore` my backup again. This time, no errors. I log in, and all users exist!  
Issue 2)  
When I try to access anything that is not the system console, I get the error page “Channel is private or does not exist. "

Checking in the system console web UI under channels, the list is empty.

I check the DB, there are channels listed.

I confirm the folder structure of the /data directory are identical from copying over and permissions are correctly set for pid 2000.

Tree view limited to 5 layers

I have no more ideas what to do and fix the missing channels. I would be very thankful for any help.

Solved the Issue for now.

I edited the `.env` file and changed the `MATTERMOST_IMAGE_TAG` from the fixed Version `10.5.2` to `latest`. Now it works, all channels are detected. Maybe this and also the other struggles I had with the import could be considered in the migration guide.
