Requirements-level migration of legacy systems

Abstract. Novel software development technologies introduce signifi-cant changes in system design, delivery and usage patterns. For many legacy applications it means that their further development becomes in-feasible due to obsolescence of technologies they use. There thus arises the need for tools supporting automated migration of legacy systems into new paradigms. In this demonstration we will show such a tool suite. Its most important characteristic is that it operates at the level of sto-ries (scenarios) traditionally produced during requirements specification. The tools highly support extracting knowledge about the functioning of legacy applications and storing them in the form of precise requirement-level models. What is more, the tools enable automated transformation of these models into object-oriented code, compliant with new system struc-ture. In the demonstration we present a recovery engine, a requirements-level editor and a transformation engine in the context of a case study example. 1 Introduction an
