Enhanced mode in AWS DataSync now supports Amazon FSx for OpenZFS as source or destination and NFS version 4.2 for on-premises and FSx file systems, allowing customers to transfer data using the latest NFS protocol versions without modification. Additionally, a new ObjectMetadata option permits control over copying user metadata during object storage transfers.

This feature addresses scenarios requiring preservation or exclusion of metadata for compatibility with destinations like AWS Storage Gateway or Azure Blob Storage. Existing DataSync tasks continue to function normally. These enhancements are accessible across all AWS Regions supporting DataSync Enhanced mode, improving data migration flexibility and control.
