Which replication methods are commonly used to migrate data from 7-Mode to Clustered ONTAP?

• A. SMB and Kerberos.
• B. FTP and SCP.
• C. iSCSI and NFS.
• D. SnapMirror and NDMP.

Answer: (D)

Migrating data from 7-Mode to Clustered ONTAP relies on NetApp-provided data transfer methods that preserve data integrity and support controlled cutover. SnapMirror is NetApp’s replication technology that copies a volume’s data to the destination and keeps it synchronized. You establish a SnapMirror relationship from the 7-Mode source to the Clustered ONTAP destination, perform an initial transfer, and then continue with periodic resyncs until you’re ready to switch over, which minimizes downtime. NDMP, the Network Data Management Protocol, is a standard backup/restore approach that NetApp integrates for migration: you back up data from the 7-Mode system and restore it onto the Clustered ONTAP system. This combination—SnapMirror for ongoing replication and NDMP for backup/restore as needed—are the common, supported methods for moving data between these platforms. Other options don’t provide the required NetApp-specific migration capabilities. SMB and Kerberos relate to access and authentication, not data transfer methods. FTP and SCP are general file-transfer tools and don’t guarantee the integrated replication, metadata handling, or coordinated cutover needed for large-scale migrations. iSCSI and NFS are data-access protocols, not dedicated migration mechanisms.
