Software-Defined-Network now a days prove to be a paradigm for Network industry. A legacy network is ruling the computer networks from decades. Legacy network's technologies and techniques are combined to secure network and making it more efficient for users. The SDN now a days emerging as replacing entity for traditional networks. SDN facilitates in terms of security to its attached appliance, traffic, policies, traffic flows and mainly its architecture. SDN provides a central management for its manageability. Security challenges in SDN Architecture attracts various stakeholders for migrating to it. Legacy network have been used with multiplatform (hardware, software) for attaining desired performance, task, security. The multiplatform hardware and software needs to be managed quite often for stability. This research work will explains how to migrate from Legacy Network to Software-Defined-Network (SDN) considering all its security perspective and how to eliminate Multiplatform of legacy network to SDN based architecture.
