ITPEC IP April 2018 Question 48
When the current system is replaced with a new system, the data to be migrated from the current system to the new system and the resources necessary for the migration are listed to create a migration plan. Which of the following is the most appropriate item to be included in the migration plan?
Explanation
Schedule and human resources for switching to the new system — a migration plan covers the move itself, from the current system to the new one.
Having listed the data to migrate and the resources required, the migration plan decides the migration method (all at once, in phases, or with parallel operation), the cutover schedule, who does each task, how the migrated data and system are verified, and how to fall back if the switch fails.
Answer (d)
Why not others:
- •(a) — functional requirements are settled in requirements definition at the start of development, long before migration
- •(b) — how to operate the new screens and forms belongs in the operation manual and user training
- •(c) — regular backups are part of the day-to-day operation of a running system, not of a one-time migration
Key rule: A migration plan covers the one-time move: method, schedule, people, data conversion, verification and fallback; how the new system works or is run day to day belongs in other documents.
