Data Migration

After you have completed the schema conversion, you’ll need to move the data itself. In case of production databases, you may not be able to afford any downtime during the migration. Moreover, you may want to keep the transactions from source and target database in sync until you switch your application to the new target.

The AWS Database Migration Service helps you migrate the data from the source database to the target database easily and securely. AWS DMS supports data migration to and from most widely used commercial and open-source databases. The source database can be located in your on-premises environment, running on an Amazon EC2 instance, or it can be an Amazon RDS database. The target can be a database in Amazon EC2 or Amazon RDS. Additionally, the source database remains fully operational during the migration, minimizing downtime to applications that rely on the database.
