Validata helps Caribbean bank complete phase 2 of Temenos core upgrade

A leading Caribbean bank has gone live with phase 2 of its Temenos core banking transformation, extending the new core to accounts and deposits. Validata says its Agentic AI platform automated testing and data migration, helping the bank lower risk as it moves through a multi-phase modernization program.

Why it matters: - The phase 2 go-live expands the bank’s modern core into accounts and deposits, a core part of day-to-day banking operations. - The transformation shows how AI-driven testing and migration tools can support large banking upgrades with less manual effort and lower operational risk. - The bank is one of the largest financial groups in the Caribbean, with more than $13 billion in assets.

What happened: - A leading Caribbean bank completed phase 2 of its Temenos core banking transformation program. - Phase 2 followed a successful phase 1 go-live. - Validata’s Agentic AI platform was used again for end-to-end testing and data migration. - The bank used the platform to support a smooth transition to the new core for accounts and deposits.

The details: - Validata’s platform automates test generation, execution and maintenance, while also detecting defects and supporting data transformation and reconciliation. - The platform uses a model-driven approach and creates a digital twin layer that sits on top of core banking systems, digital channels and third-party applications. - The bank used a phased coexistence model for data migration across three distinct phases. - High-performance staging capabilities supported end-to-end migration automation. - The migration process included reconciliation, auditability, historical data preservation and governance controls. - Automated functional, regression and performance tests now run in the bank’s CI/CD pipeline with every build and release. - Test coverage extends to digital channels, including mobile banking, so customer journeys can be validated from the mobile app through to the core. - Built-in test data management and synthetic test data generation supported the testing program. - The regression suite created across phases 1 and 2 now belongs to the bank and can be reused for future phases, upgrades and releases. - Phase 2 also aligned with the bank’s move from the Temenos Browser interface to Temenos Explorer. - The model-driven setup allowed the bank to test the new interface by reusing existing business models instead of rebuilding scripts. - After structured training and knowledge transfer from Validata, the bank’s QA team now runs testing independently in-house.

Between the lines: - The project suggests the bank is treating modernization as an ongoing operating model, not a one-time implementation. - Reusable models and an in-house QA team reduce dependence on outside support after each release. - Validata is positioning Agentic AI as a way to keep quality and migration work moving as systems change, rather than only at go-live.

What’s next: - The bank is moving through a three-phase data migration approach, so more program work remains ahead. - Validata said it will continue supporting the bank as a strategic partner. - Future phases, interface changes and new digital services can reuse the automation assets built during phases 1 and 2. - More information is available in Validata’s announcement.
