Which prerequisite ensures data continuity when migrating volumes to the new cluster?

• A. Power off the old cluster and disconnect drives.
• B. Create new empty volumes on the new cluster.
• C. Move volumes from the old nodes to the new nodes.
• D. Physically duplicate the disks into the new chassis.

Answer: (C)

Moving the volumes from the old nodes to the new nodes is the prerequisite that ensures data continuity during a cluster migration. By relocating the actual volume objects, you preserve the data, their metadata, snapshots, permissions, and client access paths, allowing clients to continue accessing the volumes with minimal or no downtime. Powering off the old cluster, creating new empty volumes, or physically duplicating disks would break access to existing data or require complete data copy/manipulation, which disrupts continuity. The volume move keeps the data intact and continually accessible throughout the transition.
