Developing a Legacy to SOA Migration Method

This document proposes a legacy to SOA migration method that can be used to extract services from legacy systems. We use the method engineering approach followed by the program slicing and concept assignment approaches to extract services from legacy codes. The proposed method is developed by reusing existing and proven parts from existing Service‐oriented methodologies, which not only saves time and reduces the adoption and introduction problems. As per our knowledge, such a method is missing until now. Our proposed method has been initially reviewed by the experts and the method was enhanced as per the findings of the experts review. Finally, the method has been successfully evaluated with a case study.
