AWS Database Migration Service (AWS DMS) now supports validation to ensure that data is migrated accurately to S3. 

If data validation is enabled for the migration then validation begins immediately after a full load is performed for a table. In the CDC phase, data validation compares the incremental changes as they occur. During data validation, AWS DMS compares each row in the source with its corresponding row at the target, verifies the rows contain the same data, and reports any mismatches.
