Abstract
The ongoing transformation of legacy systems to cloud platforms has become an integral part of contemporary enterprise strategies. In particular, the transition of PeopleSoft systems to Oracle Cloud Infrastructure (OCI) represents a pivotal case study in process optimization, cost efficiency, and scalability for organizations. This paper presents a methodological guide for the transition of PeopleSoft applications to Oracle Cloud, focusing on process-oriented workflows, application module migration, and process transition strategies. Leveraging key frameworks, including the “Lift-and-Shift” approach (Sravanthi Gondi, 2025), this study explores the technical and functional aspects of migration, assessing both the challenges and benefits of this migration strategy. By evaluating the theoretical underpinnings of cloud adoption, including the NIST definition of cloud computing (Mell & Grance, 2011), and comparing various cloud platforms (Peng et al., 2009), the paper provides a thorough examination of the migration process. Case studies and real-world examples illustrate the practical implementation of migration processes, underscoring the efficiency gains and performance improvements observed. Critical analysis of the functional components of PeopleSoft and their transition to the cloud reveals significant implications for both technical teams and business stakeholders. The study concludes by offering insights into future research directions and providing actionable recommendations for organizations aiming to modernize legacy systems through Oracle Cloud.
