What is the primary purpose of a cutover plan in data migration?

• A. To switch production to the new system and minimize downtime.
• B. To validate data in sandbox only.
• C. To map data fields.
• D. To design user interfaces.

Answer: (A)

Coordinating the final switch from the old system to the new one in production with minimal downtime is the core aim of a cutover plan. This plan specifies the exact moment to switch, the sequence of cutover tasks, who signs off on the go/no-go decision, and how data is handed over, validated in production, and rolled back if something goes wrong. By outlining the switch window, dependencies, and success criteria, it ensures business operations continue smoothly and data integrity is preserved during the transition. Other activities like validating data in a sandbox are pre-cutover tests, so they don’t govern the live switch. Mapping data fields is part of the data design and ETL planning, not the actual cutover execution. Designing user interfaces happens earlier in the project and is unrelated to the live transition of systems.
