For MongoDB Community alternatives, import a representative collection rather than a tidy demo dataset.
- Include nested documents, missing fields, arrays, and varied document sizes.
- Recreate critical indexes, aggregation pipelines, and update operations.
- Test concurrency, transaction boundaries, backup, and restore.
- Measure read and write latency under the expected workload.
- Verify driver compatibility and export to an open format.
A bulk import that succeeds does not establish equivalent query results. Record mismatches before rewriting application logic.
