Abstract. Migration of legacy assets to SOA embodies a key software engineering challenge namely rehabilitation of pre-existing enterprise assets into service based systems. Existing service analysis and design methods mostly focus on development of new services while they lack in transforming services from already existing enterprise assets. We argue that, a comprehensive SOA migration methodology is essential for creating a well-constructed SOA out of pre-existing enterprise assets. To this end, the necessary knowledge concerning the migration should be identified, captured, analyzed and generalized. We propose an approach for migration that exploits relevant knowledge to transform an existing legacy system into a new service-enabled system. For this purpose, we will devise a reference knowledge model capturing types of knowledge that drive SOA migration. 1
