The Challenges
-
High-Velocity Migration: The team was operating on a weekly release cadence during the Oracle Fusion migration, which the existing manual testing methodology could not support.
-
Complexity of Scope: Moving critical financial data and processes to the cloud required deep, repeatable validation that manual efforts couldn't reliably provide.
-
Post-Migration Sustainability: Beyond the initial migration, the team needed a strategy that could sustain faster release cycles and the mandatory quarterly Oracle releases.
-
Coverage Gaps: New tests were required every quarter to cover major Oracle releases, adding to an already heavy manual workload.
Summary
As a global leader in financial services, Citi required a highly resilient testing strategy to manage its complex migration to Oracle Fusion. To maintain security, compliance, and speed, they moved from manual validation to a cloud-ready automation framework using Tricentis Tosca.

The Outcomes
-
Immediate Time Recovery: Shifting to automation saves the team 18+ hours every week, allowing resources to focus on high-level migration strategy rather than repetitive execution.
-
Significant Project Savings: The project is on track to save over 1,800 manual hours throughout the duration of the Oracle migration.
-
Seamless Pipeline Integration: With automation integrated into the CI/CD pipeline, Citi can now validate weekly code moves with confidence and speed.
-
Quarterly Readiness: The team is now equipped to handle major quarterly releases without the traditional "testing bottleneck," ensuring long-term stability post-migration.
