What is MoDisco

Modernization of legacy systems is a new research area in the software industry intended to provide support for transforming an existing software system to a new one that satisfies new demands. This chapter analyzes software modernization based on the Architecture Driven Modernization (ADM). In this context, software modernization is supported by metamodels to describe existing systems, discoverers to automatically create models of these systems and, tools to understand and transform complex models created out of existing systems. This chapter provides an overview of the-state-of-the-art in ADM-based software modernization techniques. Taxonomy of different techniques is described. A description of how traditional techniques such as static and dynamic analysis can be integrated with ADM standards is presented. This chapter also analyzes current challenges and strategic directions in software modernization.
