Which action would undermine data preservation during the upgrade process?

• A. Move volumes from old to new nodes.
• B. Leave existing volumes intact and emulate migration.
• C. Test access to migrated data on the new cluster.
• D. Reformat the new cluster and recreate all volumes.

Answer: (D)

Preserving data during an upgrade means keeping existing data intact while transitioning to a new cluster. Reformatting the new cluster and recreating all volumes would erase all data on that cluster, wiping out what you’re trying to preserve. That action effectively starts over and defeats the upgrade’s purpose of moving and validating data from the old system. The proper approach is to migrate volumes to the new cluster (or emulate the migration to plan and verify) and then test access to the migrated data on the new system to ensure everything remains intact and usable. Moving volumes and validating access preserves data, while reformatting would destroy it.
