Migration Overview

This section provides high-level guidance for customers looking to migrate their PostgreSQL database to Amazon RDS for PostgreSQL using homogeneous data migrations in Amazon DMS.

Amazon DMS creates a serverless environment for your data migration. Depending on the type of your data migration, Amazon DMS automatically chooses an appropriate native PostgreSQL database tool.

For full load migrations, Amazon DMS uses pg_dump and pg_restore.

For full load and change data capture (CDC) migrations, Amazon DMS uses pg_dump, pg_restore, and a publisher and subscriber model for logical replication.

For homogeneous data migrations of the change data capture type, Amazon DMS configures the data replication from the start point that you provide in settings.

The following diagram illustrates how Amazon DMS migrates data from PostgreSQL databases with homogeneous data migrations.
