AWS Database Migration Service

AWS Database Migration Service (AWS DMS) is a managed service that simplifies and automates the migration of databases to AWS. It supports homogeneous migrations (e.g., Oracle to Oracle) and heterogeneous migrations (e.g., Oracle to Amazon Aurora) with minimal downtime. The service handles schema conversion, data replication, and continuous data synchronization during the migration process.
