ITPEC IP October 2022 Question 46
A system migration plan was created for the migration from an existing system to a new system. Which of the following is an appropriate item to be described in the system migration plan?
Explanation
Schedule for parallel operation of the old and new systems — a migration plan says how and when work moves from the old system to the new one.
In parallel operation both systems run for a set period, so their results can be compared and the old system remains a fallback if the new one fails. A migration plan therefore covers the migration method and schedule, data conversion, cutover, verification, fallback procedures and responsibilities.
Answer (b)
Why not others:
- •(a) — a system selection policy is decided during procurement, when choosing which system to adopt, long before migration
- •(c) — quality evaluation criteria for deliverables belong in the quality management plan of the development project
- •(d) — members' work histories are staffing information and say nothing about how to migrate
Key rule: A migration plan covers the move itself: the method (parallel, phased or all at once), schedule, data transfer, cutover and fallback.
