True or False: One of the recognized strategic options for legacy system management is to replace all or part of a system, and this option is typically appropriate when off-the-shelf software would let the new system be developed at reasonable cost, or when factors like new hardware mean the old system can no longer continue operating.
Correct Answer
Explanation
Replacement is one of the four strategic options for legacy systems and should be chosen specifically when factors such as new hardware mean the old system cannot continue, or where off-the-shelf systems allow cost-effective replacement, often using an evolutionary strategy that reuses components wherever possible.
