| Fact | Amazon Database Migration Service | Ora2Pg |
|---|---|---|
| Purpose | AWS DMS migrates relational databases, data warehouses, NoSQL databases, and other data stores to AWS or between cloud and on-premises setups. | Ora2Pg scans Oracle databases, extracts their structure or data, and generates SQL for PostgreSQL. |
AWS DMS suits teams migrating or modernizing databases and analytics workloads to AWS, including teams moving from self-managed databases to managed AWS databases. It is less suited to on-premises-to-on-premises replication.
It suits teams planning Oracle database migration to PostgreSQL, including those that want to assess migration effort or export selected data. It is a fit for users able to manage a self-hosted tool and its migration dependencies.
