Migration and Transfer
AWS DMS and AWS SCT
Guide-listed database migration tools: AWS Database Migration Service moves data, while AWS Schema Conversion Tool converts supported schema objects when source and target engines differ.
Key points
- DMS supports migrations with limited downtime through ongoing replication for supported sources and targets.
- SCT assesses and converts schemas and code objects when changing database engines.
- A same-engine migration may need DMS without schema conversion.
- The live CLF-C02 guide names AWS SCT; current DMS guidance recommends DMS Schema Conversion for new projects and treats SCT as a legacy alternative.
Best-known use cases
- Replicate data from an existing database to AWS.
- Convert a schema before a heterogeneous database migration.
What candidates often confuse it with
- DMS moves data; schema-conversion tools convert schemas.
- Recognize AWS SCT for the live exam while using current DMS Schema Conversion guidance for new projects.
- AWS CAF guides organizational adoption and does not perform database replication.
Key Cloud Practitioner takeaway
For CLF-C02, recognize DMS for data movement and AWS SCT for schema conversion; for a new real project, evaluate current DMS Schema Conversion guidance.
