AWS DMS introduces data resync for improved migration accuracy

AWS Database Migration Service (AWS DMS) now supports data resync, a new feature that automatically corrects data inconsistencies identified during validation between source and target databases.

Data resync integrates with your existing DMS migration tasks and supports both Full Load and Change Data Capture (CDC) phases. It uses your current task settings—including connection configurations, table mappings, and transformations—to apply corrections automatically, helping ensure accurate and reliable migrations without manual intervention. With data resync, AWS DMS can detect and resolve common data issues, such as missing records, or mismatched values, based on validation results.

Data resync is available starting with AWS DMS replication engine version 3.6.1, and currently supports migration paths from Oracle and SQL Server to PostgreSQL. For detailed information on how Data resync enhances migration accuracy, please refer to the AWS DMS Technical Documentation.
