With the use of Cloud Computing as a method of delivering information infrastructure resources, the enterprise may move legacy applications to the cloud in order to achieve a variety of benefits. There are many ideas in the literature to model the essential elements of migration, all of which have been confirmed through concrete case studies. A variety of reference models have also been identified in addition to these proposals which have been developed with the goal of consolidating the various researches and attempting to extend their applicability. Based on the above, this paper chooses a reference model for migration of legacy systems to the cloud and suggests a framework for estimating the perceived risk score for each legacy system migration. The paper provides a proof of concept on the government sphere to explain the method's applicability. Keyword phrases: cloud computing, legacy networks, migration, comparison model, risk perception.
