In intra-company IT environment, the use of open-source software (OSS) should be expanded to reduce IT costs and to establish SW governance. This requires the migration of systems from the existing commercial SW to open-source SW, but the attempt of application replatform is prevented by the expenses for application reprogramming and data migration. This study proposes a methodology for TCO calculation of application replatform using open-source SW. In practice, a five-year TCO shows a cost reduction effect of 78% - 83%. This TCO could be further reduced if the application size is increased due to data accumulation and the company gets open-source SW capabilities internally. In addition, it is possible to directly apply an application developed from open-source SW to a virtualized infrastructure environment, which enables to operate in a hybrid cloud environment. This enables a scalable, efficient and flexible IT operation and a sustainable TCO reduction in the future
