# DMS Replication Configuration

DMS Replication Configuration in AWS defines the settings for a Database Migration Service replication task. It specifies how data is migrated or replicated between source and target databases, including task settings, migration type, and replication instance details. This configuration controls the behavior of ongoing replication or one-time migrations.

```
aws.dms_replication_config
