Abstract
The rapid advancement of web technologies coupled with evolving business needs make legacy transformation a necessity for enterprises around the world. However, the risks in such a transformation must be mitigated with an approach that is flexible enough to allow for a gradual and low risk transformation process. This paper presents a Service Oriented Architecture (SOA) workflow-based legacy transformation approach that allows for phased transformation in which a legacy system is first transformed into self-contained modular services accessible via a dedicated service layer. These modular services are managed through an AI-enabled workflow management layer that interacts with improved UI frontend for the system's end users. This paper presents a hypothetical prototype in which an Oracle 5 legacy system is transformed using the proposed architecture. ASP.NET Core MVC as well as Pega business process management platform are utilized to practically assess the feasibility of the proposed approach.
