# Database Migration Service Data Migration Task

An AWS Database Migration Service Data Migration Task defines the actual migration job that moves data between a source and target database. It specifies details such as the migration type (full load, ongoing replication, or both), the mapping of tables, and transformation rules. This task runs within a replication instance and manages the flow of data, ensuring that databases are synchronized with minimal downtime during migration.
