Amazon Database Migration Service is a managed web service that enables you to migrate data from a source database to a target database. To initiate the connection between the two data stores, transfer the data, and cache any changes that occur on the source data store during the initial data load, an AWS DMS replication instance is used. The DMS service regularly releases engine version upgrades to introduce new software features, bug fixes, security patches, and performance improvements.
