ITPEC FE Morning April 2021 Question 56
ITPEC FE Morning April 2021 — Question 56 of 80
A migration test verifies the procedure for switching from the existing system to the new system and identifies reliability and efficiency problems that the switch may cause.
- •Migration test — validates the cutover process itself (data transfer, rollback plans, downtime impact)
- •Function test — confirms the new system has all required features
- •Performance test — checks throughput using real data copies
- •Integration test — verifies interface compatibility between systems
Why not others:
- (a) — describes a function test (does the system do what it should?)
- (b) — describes a performance test (can it handle real workloads?)
- (c) — describes an integration test (do interfaces between systems work?)
Key rule: Migration test = testing the switch procedure, not the system's features or performance.
