Technology leading nations recognized the importance of cloud computing and are implementing cloud-first policies to innovate in the public sector and competitiveness of their own companies. In particular, the United States implemented cloud computing environment in the defense sector in 2008. US Department of Defense said it increased defense work efficiency and reduced costs by 25~50% as a result. The Ministry of Defense of South Korea also needs to develop migration methodology and procedures suitable for the defense environment based on the US Department of Defense's case in order to reduce costs and improve work efficiency. Based on the migration methodology and procedures, it is need to migrate legacy Command and Control system to cloud environment firstly. In this paper, we proposed the considerations in migrating the legacy command and control system service to the cloud computing environment based on the defense informatization business process and the industry's cloud migration procedure. And we also proposed a cloud migration methodology according to business requirements and period, business cost, cloud infrastructure environment status and a cloud migration environment establishment procedure.
