%X The Replacement of a legacy system with newly reengineered Information System has always been a challenging task. The end-users and the integrated software environment of legacy system make things harder for the deployment team. The legacy data migration challenge complicates the very important deployment phase. In this paper however, we have discussed and analyzed three different strategies to deploy a newly reengineered Information System and replace the legacy system in a homogeneous environment. This paper mainly addresses the issues concerning minimum disturbance to the legacy environment and smooth deployment of the new Information System. It is pertinent to mention that the issues regarding the development of reengineered information system or the legacy data migration have not been discussed here. At the end we have provided a detailed analysis and finally recommended the most optimal strategy among all. The rationale behind the suggested solutions is an extensive study conducted at our research and development Lab.
