Key points

• Continuous change capture can reduce migration downtime after an initial load.
• Homogeneous migrations focus on moving data; heterogeneous migrations add schema and application compatibility work.
• DMS task monitoring, source/target capacity, networking, and validation determine migration quality.

Best-known use cases

• Move a database to RDS or Aurora with limited downtime.
• Replicate supported database changes into an analytical target.

What candidates often confuse it with

• DMS moves database data; schema conversion addresses incompatible database objects during heterogeneous moves.
• Application Migration Service replicates servers; DMS replicates database data.

Key takeaway

Choose DMS for supported database data movement and replication, while planning schema/application work separately.
