Original report: https://github.com/mattermost/mattermost-server/issues/15531 … **Summary** PostgreSQL is the preferred database for Mattermost, and there should be a supported upgrade path to it. **Possible fixes** As per related issue [#4911](https://github.com/mattermost/mattermost-server/issues/4911], pgloader seems to be the tool of choice for migrating to PostgreSQL. It would be great if the Mattermost team could provide [a load command file|https://pgloader.readthedocs.io/en/latest/tutorial/tutorial.html#id13) for it. This would enable the admin to create a new install (of the same version) so that so the schema can be known correct, then the tool need only migrate the data across. ---- If you're interested please comment here and come [join our "Contributors" community channel](https://community.mattermost.com/core/channels/tickets) on our daily build server, where you can discuss questions with community members and the Mattermost core team.
