How a Global Energy Enterprise Migrated from PeopleSoft to Oracle HCM

Customer Background

A 173-Year-Old Energy and Technology Leader Modernizing HR

A global technology and energy organization with more than 173 years of history is advancing its mission to integrate digital and physical systems. The company delivers technology solutions across healthcare, industrial transformation, infrastructure, mobility, and energy transition initiatives.

As part of this growth, managing a global workforce of over 293,000 employees became a critical priority. Leadership migrated from PeopleSoft HRMS to Oracle Fusion HCM to support modern business requirements and future growth, and then needed to move a large volume of PeopleSoft reports onto the new platform without disruption.

The Challenge

A Complex, National-Scale PeopleSoft-to-Oracle HCM Transition

The customer needed a partner who could handle the scale and complexity of the transition while unlocking the reporting capabilities Oracle Fusion HCM promised, with zero tolerance for defects along the way.

Massive scale

A workforce of more than 293,000 employees spanning healthcare, industrial, infrastructure, mobility, and energy businesses worldwide.

Aggressive timelines

A large volume of PeopleSoft reports had to be converted and validated on a tight schedule.

Data mapping

PeopleSoft's data model rarely maps one-to-one onto Oracle HCM, so each report had to be reviewed and mapped to Oracle HCM entities, not just transferred.

Product gaps

Several required columns and parameters were not available in the HCM Extract user entities. To close these gaps, DataTerrain developed custom fast formulas and value sets to derive the required values.

Redundant reports:

Many legacy reports shared near-identical columns, adding maintenance overhead that needed rationalizing.

Zero-defect delivery

Predictable timelines and budget adherence, with no room for error in the final reports.

Our Approach

DataTerrain's Expedited Transition Framework

DataTerrain's proprietary framework guided the transition, chosen for its deep technical expertise, pre-built Oracle HCM report accelerators, and track record of zero-defect delivery at pace.

1

Analysis and Mapping

DataTerrain cataloged every PeopleSoft report and mapped each to Oracle HCM entities, and new report designs were approved by stakeholders before development.

2

Automated Report Conversion

Reports were built with the best-fit method for each need: OTBI analyses, BI Publisher reports with custom layouts, and HCM Extracts or Excel outputs. DataTerrain's automation engine accelerated the delivery, and overlapping legacy reports were merged into single, multi-layout HCM Extracts to simplify long-term maintenance.

3

Report Validation

DataTerrain's custom-built testing apps compare converted reports against source reports for format, layout, and data accuracy, catching issues early. Where product gaps surfaced, DataTerrain raised service requests with Oracle and applied patches, with documentation supporting the move from test to production.

4

Acceptance and Rollout

Validated reports moved to pre-production for final checks, then to Oracle HCM production after acceptance. DataTerrain managed HCM Extract and OTBI scheduling, resolved post-go-live issues with end-user sign-off, and ran knowledge-transfer sessions with documentation handover.

Business Impact

Outcomes That Mattered to the Business

The transition was completed on schedule and within budget, spanning 110+ reports (80+ converted, 30+ newly created).

Zero-Defect Delivery

Pixel-perfect contractual and statutory reports delivered with no errors.

Faster Time-to-Value

Pre-built, PeopleSoft-equivalent reports cut development time by approximately 89%, from an estimated 3,520 hours to about 400 hours.

Oracle Issues Resolved

DataTerrain's Oracle partnership resolved platform defects and performance issues directly.

Self-Service Enabled

OTBI dashboards were configured for ad hoc reports, alerts, and analysis.

Quick Payback

The customer achieved fast ROI and continues expanding Oracle HCM globally.

Bottom Line

Why choose DataTerrain

DataTerrain added value beyond delivery by acting as a single point of coordination with Oracle to resolve product issues, reducing cost, effort, and delays for the customer.
