AWS Database Migration Service (DMS)
Migrate your databases to AWS quickly, securely, and with minimal downtime.
What is AWS Database Migration Service (DMS)?
AWS Database Migration Service (AWS DMS) 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. AWS DMS supports homogeneous migrations (such as Oracle to Oracle) as well as heterogeneous migrations between different database platforms (such as Oracle to Amazon Aurora or Microsoft SQL Server to MySQL).
Key Features
- Minimal downtime during migration
- Support for homogeneous and heterogeneous migrations
- Continuous data replication for zero downtime
- Schema conversion for heterogeneous migrations
- Support for most popular commercial and open-source databases
- Simple to set up and monitor
How AWS Database Migration Service (DMS) Works
Stage 1: Create Replication Instance
Create a replication instance that performs the migration tasks and handles the data transfer between source and target databases.
Stage 2: Define Endpoints
Define source and target endpoints that provide connection information for your source and target databases.
Stage 3: Create Migration Task
Create a migration task that specifies what tables to migrate, any transformations to apply, and whether to migrate existing data, replicate ongoing changes, or both.
Stage 4: Monitor and Cutover
Monitor the migration progress, validate data, and perform the final cutover when you're ready to switch your applications to the target database.
Benefits of AWS Database Migration Service (DMS)
Minimal Downtime
Keep your applications running during migration with minimal disruption to normal operations.
Simplified Migration
Automate complex migration tasks with a simple, easy-to-use service that requires minimal expertise.
Cost-Effective
Pay only for the resources used during migration, with no upfront costs or long-term commitments.
Reliable
Benefit from a service that has migrated thousands of databases to AWS with high reliability and data integrity.
Secure
Protect your data during migration with encryption in transit and integration with AWS security features.
Flexible
Migrate between same-type databases or convert schemas between different database platforms to suit your needs.
Common Use Cases
Cloud Migration
Migrate on-premises databases to AWS cloud databases to reduce infrastructure costs and management overhead.
Database Platform Change
Migrate from commercial databases to open-source or AWS-managed database services to reduce licensing costs and vendor lock-in.
Database Consolidation
Consolidate multiple databases into a single database or data warehouse to simplify management and reduce costs.
Continuous Replication
Set up ongoing replication between databases for disaster recovery, read scaling, or data distribution across regions.

Frequently Asked Questions
What databases does AWS DMS support?
AWS DMS supports most popular commercial and open-source databases, including Oracle, Microsoft SQL Server, MySQL, PostgreSQL, MariaDB, MongoDB, SAP ASE, IBM Db2, and Amazon's database services like Aurora, RDS, Redshift, DynamoDB, and DocumentDB.
How does AWS DMS handle schema conversion?
For heterogeneous migrations (between different database engines), AWS DMS works with AWS Schema Conversion Tool (AWS SCT) to convert database schemas and code objects to a format compatible with the target database. AWS SCT can also identify objects that cannot be automatically converted, providing guidance for manual conversion.
What is the difference between full load and CDC?
AWS DMS offers two migration methods: Full Load, which migrates existing data from the source to the target database, and Change Data Capture (CDC), which captures ongoing changes to the source database and applies them to the target. You can use Full Load only, CDC only, or both together for a complete migration with minimal downtime.
How much downtime is required during migration?
With AWS DMS, you can minimize downtime to just the time it takes to redirect your applications from the source to the target database. By using Full Load + CDC, AWS DMS first copies existing data, then captures and applies ongoing changes, allowing you to keep your source database operational until you're ready to switch over.
How is AWS DMS priced?
AWS DMS pricing is based on the replication instance type you use (which determines compute and memory resources), storage used for replication logs, data transfer between Availability Zones or regions, and any additional features like AWS SCT. There are no upfront costs or long-term commitments.
