As the post explained, one of the big problems of migration off of MongoDB is finding out the "effective" schema of the data, and then migrating it (according to that schema). By "effective" I mean the resulting structure of the data stored in the database. I think it would very helpful to use here ToroDB (https://github.com/torodb/torodb https://github.com/torodb/torodb). While being MongoDB-compatible, it stores data structured into PostgreSQL tables, automatically identifying the schema of the data. Then, just by looking at the created tables, you very easily have the schema (and the data migrated to that schema). It would make migration easier. Disclaimer: I am a ToroDB developer
