   A large enterprise is migrating a mission-critical database volume from an older VMAX to a new PowerMax. The database has a strict RPO/RTO of zero, meaning no data loss or downtime is acceptable. The storage team has verified compatibility and capacity. During the migration, the source volume will continue to receive writes. What is the key mechanism that ensures no data is lost during the migration?

   • AThe migration creates a full copy of the source volume at the start, and all subsequent writes are only applied to the source.
   • BThe migration pauses all writes to the source volume during the copy phase, ensuring a consistent snapshot is created.
   • CThe migration uses a snapshot of the source volume, and the application is briefly paused during cutover to apply the final writes.
   • DThe migration continuously tracks and copies all new writes to the target volume until cutover, ensuring the target is always synchronized.
