An organization is implementing a new system to replace a legacy system. Which of the following
conversion practices creates the GREATEST risk?

A.
Pilot

B.
Parallel

C.
Direct cutover

D.
Phased

Explanation:
Direct cutover implies switching to the new system immediately, usually without the ability to revert
to the old system in the event of problems. All other alternatives are done gradually and thus provide
greater recoverability and are therefore less risky.
