An important problem that many large organizations face today concerns the support and evolution of their large (legacy) information systems. In this paper we present an approach for migrating large and interdependent legacy information systems to CORBA based platforms. Our approach allows continuous availability of the information systems, minimal manpower for the implementation and preservation of the autonomy of the independent information systems. The information systems of ABB AG serve as case study for the presentation of our approach.
