Which of the following operations can ensure data synchronization between the production end and DR end during planned migration of CSDR?

1. A. Create a snapshot for the ECS or BMS at the production end, synchronize the data before the snapshot to the DR end, and repeat this operation to complete data synchronization in iterative migration mode.
2. B. After the planned migration is triggered, attach the disks at the production and DR ends to the ECS or BMS at the same time. Data is written to the disks in dual-write mode. Then, detach the disks at the production end.
3. C. The first step of planned migration is to stop services on the ECS or BMS at the production end to prevent data changes. — đáp án hiện tại
