Which is the correct description of the NDVM phases?

• A. They consist of Setup Phase, Data Copy Phase, and Cutover Phase
• B. They consist of Setup Phase, Mirror Phase, and Cutover Phase
• C. They consist of Initialization Phase, Copy Phase, and Migrate Phase
• D. They consist of Begin Phase, Move Phase, and Complete Phase

Answer: (A)

NDVM stands for Non-Disruptive Volume Migration, and its lifecycle is built around three clear phases to minimize downtime during a volume move. The Setup Phase prepares the destination environment—provisioning the target volumes, configuring NDVM, and validating connectivity and prerequisites so the migration has a solid foundation. The Data Copy Phase is where the actual data moves: data is copied to the destination while the source remains online, with ongoing changes replicated so the destination stays nearly current. The Cutover Phase switches production to the destination, performs a final synchronization and validation, and completes the migration by decommissioning or reconfiguring the source as needed. This three-phase flow—setup, data copy, and cutover—best matches how NDVM is designed to operate. Other options use terms like Mirror Phase or Begin/Move/Complete that aren’t the standard NDVM phase names.
