Navigating the Oracle EBS 12.1.3 to 12.2.8 Upgrade: Key Strategies for a Smooth Transition

Abstract

As Oracle EBS 12.1.3 reaches the end of Premier Support, enterprises are compelled to modernize toward Oracle EBS 12.2.8—offering online patching, a restructured stack, and enhanced modules. This paper dissects the upgrade journey, emphasizing architectural shifts like Edition-Based Redefinition (EBR), custom code remediation, and third-party integration challenges.
Using a mixed-method approach—literature review, case study, and ROI modeling—this study highlights dual filesystem architecture, WebLogic adoption, and Oracle ADOP for patching automation. It serves as a strategic guide for CIOs and IT leaders seeking performance, compliance, and maintainability improvements.
