Many enterprise IT systems contain applications that have evolved over twenty years or so, often with poorly structured and undocumented code. Such applications are neither manageable nor modifiable. On the other hand, replacing these applications in one go with a big-bang implementation is too risky. Companies need a way to re-engineer their IT systems with modern software technology. This must allow old and new programs to co-exist, and must allow successive decommissioning of older applications.

We have been engaged in automating development of legacy IT systems for the past six years. In this session, we demonstrate the techniques that have been successfully applied to six IT projects for a variety of applications in treasury products, payments, credits and securities. The techniques presented can be applied to re-engineering and development of any enterprise IT system, independently of programming language.
