What is an evolutionary replacement strategy in the context of legacy system replacement?

The system is replaced exclusively using genetic algorithms to generate new code

Major system components are replaced by off-the-shelf systems while other components are reused wherever possible

Only the user interface is ever changed, while all backend logic remains forever

The entire system is replaced overnight with zero testing of any kind

Correct Answer

Major system components are replaced by off-the-shelf systems while other components are reused wherever possible

Explanation

In an evolutionary replacement strategy, major system components are replaced by off-the-shelf systems, while other components that still function well are reused wherever possible. This balances risk and cost compared to a complete from-scratch rebuild.
