The management can follow the steps below to ensure that the legacy systems continues to cater for the dynamic modern environment:
1. Continue maintaining the legacy system as it is.
2. Perform some re-engineering (system improvement) that makes the system easier to maintain and continue maintenance.
3. Encapsulate the existing functionality of the system in a wrapper and add new functionality by writing new code which calls on the existing system as a component.
4. Decompose the system into separate units and wrap them as components. This is similar to the solution above but gives more flexibility in how the system is used.
