Network Attached Storage (NAS) to Cloud data migration is the process of moving data from an on-premises data center to a cloud. It requires data to be moved from a file format (NFS or SMB) to an Object/Cloud format such as S3. A high-fidelity NAS-to-Cloud migration solution preserves all the file metadata including access control and privileges in the cloud. This enables data to be used either as objects or as files in the cloud.
