Case Study: Leading Generation and Transmission Utilities Company achieves efficient, integrated Oracle EBS 12.2.9 and 19c upgrade with DatAvail

Datavail helped use industry best practices to create an efficient and integrated system

Leading Generation and Transmission Utilities Company, a generation and transmission cooperative serving approximately 432,000 homes and businesses (~$800M revenue), needed to modernize its legacy Oracle environment. The customer engaged Datavail to upgrade Oracle E-Business Suite from 12.1.3 to 12.2.9 and move the Oracle Database from 11g/12c to 19c. Key challenges included EBS compatibility with the CDB/PDB multi-tenant architecture, OAF page/controller changes that impacted the iProcurement module, and fragile integrations that relied on a custom external FTP server.

Datavail executed a phased implementation using its Unified Implementation Methodology (hybrid Agile/Waterfall), installing the 12.2 application file layout and patches, upgrading the database path to non-CDB 19c and EBS 19c PBD, rebuilding OAF customizations, coordinating Oracle fixes, and moving integration files to the fs_ne file system while updating Unix shell scripts and maintaining separate test/prod bundles. Datavail’s work resulted in a successful upgrade to Oracle EBS 12.2.9 and Oracle 19c, stabilized integrations to prevent file-system swap interruptions, and improved operational readiness and maintainability for the customer’s ERP environment.
