Which NetApp practice supports data preservation during node migration?

• A. Manual re-creation of volumes on the new cluster.
• B. Moving the volumes from the old nodes to the new nodes.
• C. Deleting the old cluster entirely.
• D. Ignoring existing data and starting fresh.

Answer: (B)

During a node migration in a NetApp clustered environment, the goal is to keep data accessible and intact as you move workloads. Moving the volumes from the old nodes to the new nodes is the approach that preserves the existing data drumbeat: it relocates ownership of the volumes to the target nodes without recreating or copying the data, often using a non-disruptive move so clients keep access with minimal downtime. This preserves the volumes’ data, configurations, snapshots, and policies exactly as they are, avoiding data loss and service disruption. Re-creating volumes would force you to bring data in from backups or copies, which introduces risk and downtime. Deleting the old cluster would wipe data. Starting fresh discards all existing data. Ignoring data isn’t a viable option in a migration.
