<a name="change-data-capture-dms-migrate"></a>

Publication date: **August 2, 2021 ([Diagram history](#diagram-history))**

This architecture shows how to use [AWS Database Migration Service](https://docs.aws.amazon.com/dms/latest/userguide/Welcome.html) (AWS DMS) for change data capture (CDC) to migrate databases using ongoing replication.

The following steps describe the architecture:

1. Sources for CDC include Oracle, SQL Server, MySQL, PostgreSQL, MongoDB, Amazon Aurora, [Amazon DocumentDB](https://docs.aws.amazon.com/documentdb/latest/developerguide/what-is.html), and Amazon RDS.

1. AWS Schema Conversion Tool makes heterogeneous database migrations predictable by automatically converting the source database schema and a majority of code objects to a format compatible with the target database.

1. AWS DMS helps you with one-time data migration of databases and continuous data replication. AWS DMS captures changes on the source database and applies them in a transactionally consistent way to the target.

1. Targets for CDC include Oracle, SQL Server, MySQL, PostgreSQL, MongoDB, Amazon Aurora, Amazon DocumentDB, Amazon RDS, and Amazon S3.
