Reimagining Government Financial Systems: A Scalable ERP Upgrade Strategy for Modern Public Sector Needs

Abstract

In an era of rapidly evolving public expectations, digital transformation, and increasing fiscal accountability, modernizing government financial systems is no longer optional—it is imperative. This research explores a scalable and sustainable strategy for upgrading legacy Enterprise Resource Planning (ERP) systems in the public sector, with a focus on transitioning from Oracle E-Business Suite R12.1.3 to R12.2.10 using Oracle Database 19c. The study examines the key drivers behind ERP modernization, including operational agility, real-time financial reporting, compliance with regulatory frameworks, and cloud readiness. Through a structured upgrade framework and a case-based approach, the paper demonstrates how a phased, minimally disruptive strategy can unlock the full potential of ERP systems while ensuring data integrity, business continuity, and long-term scalability. Technical insights, including online patching architecture, database optimization, and enhancements in user experience, are discussed to highlight the feasibility of this upgrade path in a government setting. The findings support the notion that with the right methodology, public institutions can reimagine their financial systems to meet modern needs—ensuring transparency, efficiency, and digital resilience.
