What operation is essential to preserve existing data when upgrading from FAS2520 to FAS8300?

• A. Deleting old volumes on the new cluster.
• B. Moving the volumes from the old nodes to the new nodes.
• C. Backing up data to external media and restoring.
• D. Formatting all disks on the new cluster.

Answer: (B)

The key idea is to preserve data by migrating what you have onto the new hardware. Moving the volumes from the old nodes to the new FAS8300 cluster transfers the actual data, its configuration, snapshots, quotas, and exports onto the new system without deleting or reformatting, so the data remains intact and immediately usable after the upgrade. Deleting old volumes would erase data, and formatting disks would destroy it, while backing up to external media and restoring adds a separate recovery path but isn’t the action that preserves the existing data on the new hardware. So, relocating the volumes to the new nodes is the essential step to keep data intact during the upgrade.
