DBConvert Streams vs Ora2Pg

DBConvert Streams is a UI-driven bidirectional MySQL ↔ PostgreSQL migration tool with validation and continuous CDC.

Ora2Pg is an open-source Perl CLI tool that migrates Oracle and MySQL databases to PostgreSQL, including PL/SQL conversion.

Quick answer

Choose by job

Choose DBConvert Streams if

  • The migration is MySQL ↔ PostgreSQL (either direction).
  • You need a UI and REST API around the migration.
  • You need resumable load, parallel writes, and validation built in.
  • You need continuous CDC after migration.

Choose Ora2Pg if

  • The source is Oracle.
  • You need PL/SQL converted to PL/pgSQL.
  • You want a free OSS CLI tool with an assessment report.
  • PostgreSQL is the only target.

AI and MCP

The AI difference

DBConvert Streams

DBConvert Streams adds interactive AI analysis, result validation, and a continuing CDC path for supported MySQL–PostgreSQL workflows rather than a conversion-only toolchain.

Where DBConvert Streams goes further

Run the migration from a UI and REST API

Configuration, table mapping, and monitoring live in the interface instead of ora2pg.conf, and everything is scriptable over one API.

Resume inside a table after failure

Checkpoints per primary-key range let eligible tables resume mid-load. Ora2Pg re-runs whole tables.

Go both directions

MySQL ↔ PostgreSQL is bidirectional. Ora2Pg targets PostgreSQL only.

Keep the target in sync after the load

Log-based CDC continues after cutover. Ora2Pg is one-shot batch migration.

Where Ora2Pg wins

Use an open-source Oracle migration CLI

Ora2Pg covers Oracle → PostgreSQL schema, data, indexes, constraints, views, and procedural-code conversion from the command line.

Note — Prefer a commercial GUI? DBConvert for Oracle & PostgreSQL also migrates and synchronizes Oracle with PostgreSQL.

Translate PL/SQL into PL/pgSQL

Ora2Pg includes procedural-code conversion with manual fixup. This capability is outside DBConvert Streams.

Workflow

Replace a one-shot CLI conversion with a migration that keeps running

  1. 1Drive schema and data migration MySQL ↔ PostgreSQL from the UI.
  2. 2Load with resumable checkpoints and parallel writes.
  3. 3Check validation views and schema diff before cutover.
  4. 4Turn on continuous log-based CDC after the cutover.

Ora2Pg is the free CLI path for Oracle and PL/SQL conversion. DBConvert for Oracle & PostgreSQL provides a commercial GUI migration and synchronization path, while DBConvert Streams focuses on MySQL ↔ PostgreSQL migration and CDC.

FAQ

Frequently asked questions

Can DBConvert Streams replace Ora2Pg?

For MySQL ↔ PostgreSQL migration, yes — and DBConvert Streams continues with CDC after the load. For Oracle, use DBConvert for Oracle & PostgreSQL; for PL/SQL → PL/pgSQL conversion, Ora2Pg remains the better fit.

Does DBConvert support Oracle as a source?

Yes, through the dedicated DBConvert product line.

  • DBConvert for Oracle & PostgreSQL — Migrates and synchronizes Oracle with PostgreSQL through a commercial GUI.
  • DBConvert Streams — Focuses on MySQL/MariaDB and PostgreSQL, plus file and S3 inputs.

What about PL/SQL → PL/pgSQL?

Procedural-code conversion is outside DBConvert Streams. Ora2Pg and AWS SCT provide dedicated PL/SQL conversion workflows.

How does Ora2Pg's resumable behavior compare?

Ora2Pg can re-run individual tables after a failure but does not checkpoint progress within a table. DBConvert checkpoints per primary-key range and resumes within a load for eligible tables (single integer PK, upsert mode, supported source/target engines); other tables run plain non-resumable copy in the same job.

Does Ora2Pg do CDC?

No. Ora2Pg is one-shot batch migration. Keeping source and target aligned afterwards is up to other tooling. DBConvert continues with log-based CDC reading the binlog or WAL.

When does each clearly win?

Ora2Pg wins when free OSS and PL/SQL conversion are required. DBConvert for Oracle & PostgreSQL wins when Oracle migration needs a commercial GUI and synchronization. DBConvert Streams wins for UI-driven MySQL ↔ PostgreSQL migration plus log-based CDC.
