About Legacy system modernisation
Old systems are rarely replaced because they stopped working. They are replaced because nobody can change them, the person who wrote them has left, and the hardware or platform is going out of support.
Modernisation is usually incremental: put an API in front of the old system, move one capability at a time, and keep the original running until each replacement has proved itself through a full business cycle.
