The aging of software is a lingering problem for many companies. We know that in new projects, Model Driven Engineering can be used to prevent this aging in the future. However, this does not solve the problems we have today with legacy information systems. We propose a general method for the modernization of legacy information systems, by transforming these systems into model driven systems. To accomplish a transformation into a model driven system, first a model is extracted from the legacy system. This model is then transformed into a model driven system, using Model Driven Engineering....
