MIMOS, System Model-Driven Migration Project

The volatile IT industry often tempts companies to replace legacy information systems with new ones. However, legacy systems cannot always be completely discarded because they gradually store a significant amount of valuable business knowledge as a result of progressive maintenance over time. Most migration techniques are proposed and applied in an ad hoc way. As a result, most migration techniques have a lack of automation and formalization, which makes it difficult to reuse such techniques to large, complex legacy information systems. This paper introduces MIMOS, a third-year project aimed at developing a methodological and technological modernization framework to facilitate the migration of legacy systems based on high-level design models. The work in progress during the first year mainly focused on the definition of a business process mining technique to retrieve the business knowledge embedded in source code so that it can be reused in the target system.
