AWS Database Migration Service

AWS Database Migration Service helps you migrate databases to AWS quickly and securely.

The source database remains fully operational during the migration, minimizing downtime to applications that rely on the database.

The AWS Database Migration Service can migrate your data to and from most widely used commercial and open-source databases.

Supported migration paths include:

  • On-premises and EC2 databases to Amazon RDS or Amazon Aurora.
  • Homogeneous migrations such as Oracle to Oracle.
  • Heterogeneous migrations between different database platforms, such as Oracle or Microsoft SQL Server to Amazon Aurora.

With AWS Database Migration Service, you can continuously replicate your data with high availability and consolidate databases into a petabyte-scale data warehouse by streaming data to Amazon Redshift and Amazon S3.

When migrating databases to Amazon Aurora, Amazon Redshift, Amazon DynamoDB or Amazon DocumentDB (with MongoDB compatibility) you can use DMS free for six months.

Use along with the Schema Conversion Tool (SCT) to migrate databases to AWS RDS or EC2-based databases.

The AWS Database Migration Service can migrate your data to and from most widely used commercial and open-source databases.

Schema Conversion Tool can copy database schemas for homogenous migrations (same database) and convert schemas for heterogeneous migrations (different database).

DMS is used for smaller, simpler conversions and also supports MongoDB and DynamoDB.

SCT is used for larger, more complex datasets like data warehouses.

DMS has replication functions for on-premise to AWS or to Snowball or S3.
