As technologies are continuously evolving, it has become almost mandatory to
update and redesign systems to be in flux. Organizations can obtain the most cost-effective
and valuable solutions by transforming their legacy assets. Reengineering the Legacy System
generally aims to lessen the cost of application maintenance and make the systems
more up-to-date and efficient. Thus, we provide an agile reengineering methodology for a
Legacy System to smoothly evolve to a new system, and simultaneously, the Model-Driven
Approach and Service Oriented Architecture (SOA) are introduced into the reengineering
process. The aim of this methodology is to use static and dynamic analysis to model the
Legacy System interface. The final output model can assist the model transformation tool
to rapidly generate a specific language interface and data service, and then join the UI and
data service under SOA. This agile reengineering methodology is a new development process
in system reengineering.
