Many enterprises and businesses are running old and legacy applications for several core business functions and eliminating or replacing the entire system are not possible at all.
Such legacy applications have code in an old style with poor readability for the contemporary developers. If we are refactoring the code and make it standard for the modern developers and programming practices, it may work better and serve for some more years/time.
Legacy applications also need to address the core aims/targets to make it functional in the current environment. Therefore, re-purposing and consolidation are essential steps to make it compatible with a modern digital environment where mobile presence and cloud technologies are ruling.
With the modernization of the application, we can create new business values from the already existing applications at minimum expenditure on the app development.
