Certified pairs pass the full live suite on real servers: schema fidelity, row counts, type-aware checksums, views compared row for row, binary data and multi-batch paging. MySQL, MariaDB, PostgreSQL and SQLite pairs re-run automatically every week; SQL Server and Oracle pairs are re-run by hand. Beta pairs (MongoDB to or from a SQL engine) are verified by row counts — review the post-migration fidelity report and validate critical data.
