Abstract

This chapter presents a case study which examines the results of a Legacy Systems Modernization (LSM) pilot project executed by Office of the Chief of Naval Operations (OPNAV), Logistics and Readiness (N40), and Naval Network Warfare Command (NETWARCOM), and sponsored by the Department of the Navy (DON). Business Innovation Team (BIT) for the purpose of creating and proving a process for migrating quarantined aged legacy applications into the Navy Marine Core Intranet (NMCI)-approved environment by automating legacy system transformation into modern languages, modern databases, and N-tiered architectures rather than through manual conversion. The pilot focused on modernizing aged applications that no longer met NMCI security requirements, and successfully demonstrated a more cost-effective automated transformation process alternative for functional area managers (FAMs) and central design agencies (CDAs), to use for modernizing workplace desktop applications than the conventional manual process. The pilot described in this case study combines the replacement and upgrade of the existing legacy engineering operational sequencing system (EOSS) into a modern NMCI compliant system with the development of a repeatable architecture-driven LSM process leveraging existing commercial technologies to demonstrate repeatable process for transforming NMCI applications with little human involvement into the desired modernized NMCI compliant applications.
