The problem

Row counts match. The data doesn't.

Migrating between database engines — Oracle to PostgreSQL, say — or between platforms is where silent data loss hides. The row counts line up, so it looks fine. But values drift, joins shift, and nulls get mangled in the translation between type systems and dialects.

A schema check and a row-count check won't catch any of that. By the time someone notices the values are wrong, the old system may already be gone.

How DataRecs helps

Prove parity, cell by cell, before you switch over

Value-level comparison across different engines — the checks a schema diff can't do.

Compare across different engines

Value-level comparison between different database engines — Postgres, Oracle, DB2, SQL Server, MySQL.

Catch what counts miss

Surface the drifted values, mangled nulls, and shifted joins that schema and row-count checks skip.

A repeatable cutover gate

Run the same reconciliation as a gate before every cutover attempt until parity is clean.

Drill down to exact mismatches

See precisely which rows and columns differ so you can fix the migration, not guess.

Prove parity before you switch

Cut over with confidence — with reproducible evidence the target matches the source.

Runs in your pipeline

Drive validation from the DataRecs CLI or Terraform provider so it runs inside CI/CD.

Wire it into CI/CD

Migration validation shouldn't be a one-off manual step. Use the DataRecs CLI and Terraform / OpenTofu provider to define reconciliation as code and run it as an automated gate in your migration pipeline.

  • DataRecs CLI for scripted, repeatable runs
  • Terraform / OpenTofu provider for infrastructure-as-code
  • Fail the pipeline when parity isn't met
  • Version-controlled, reproducible validation

Don't cut over on a hunch

Run a value-level reconciliation between your old and new systems and see exactly where they differ — before you switch off the source.
