Database Migration MariaDB to PostgreSQL

Since there are Rumors Mattermost is dropping MariaDB Support I would like to
migrate my MariaDB Mattermost installations to PostgreSQL. I have read some old Articles about, but there is no official procedure…

Or did I miss something? Anyone has done this recently?

I haven’t done that and it might be complicated depending on the amount of data in your database (extensions, etc.).

But newer versions support an export and import task using the command line utility mmctl, which basically dumps all the information into a JSONL format and therefore supports cross-database transfers.

Worth a try, I think.

@manuel46: See Migrating from MariaDB to PostgreSQL DB - #3 by agriesser if this is still relevant for you.
