What is the primary purpose of staged migrations when moving legacy addresses to a new system?

• A. Gradual rollout via staged migrations
• B. One-shot migration
• C. Ignore rollback plans
• D. Skip data cleansing

Answer: (A)

Staged migrations are about rolling the change out in small, controlled steps rather than all at once. This lets you validate data transformations and system integrations step by step, so you can catch and fix issues early without disrupting the entire operation. By migrating in chunks, you limit the blast radius if something goes wrong, making rollback or targeted fixes much easier and safer. It also allows ongoing data cleansing and reconciliation to happen incrementally, and gives users time to adapt to the new system while keeping business processes running. In short, the goal is to minimize downtime and risk while preserving data quality and continuity during the transition.
