Abstract

Future Internet technologies necessitate dramatic changes in system design, delivery
and usage patterns. For many legacy applications it means that their further
development and transition to the Internet becomes problematic or even
impossible due to the obsolescence of technologies they use. Replacement of
the old system with the new one, built from scratch, is usually economically
unacceptable. Therefore, there is a call for methods and tools supporting
the automated migration of legacy systems into a new paradigm. This paper
proposes a tool supported method for recovery and migration of application
logic information from legacy systems. The information extracted from a legacy
application is stored in the form of precise requirement-level models enabling
automated transformation into a new system structure in a model-driven way.
Evaluation of the approach is based on a case study legacy system.
