Validata powers Phase 2 of a Caribbean bank’s Temenos core overhaul

A leading Caribbean bank has completed Phase 2 of its Temenos core banking transformation with Validata’s agentic AI platform, extending the new core to accounts and deposits. The rollout adds automated testing and data migration across digital channels, while the bank’s QA team now runs the process independently.

Why it matters: - The Phase 2 go-live shows how a large bank can expand a core banking transformation without adding as much manual testing and migration risk. - The program covers accounts and deposits, which are central to day-to-day banking operations and customer experience. - The bank’s QA team now owns the automated testing process internally, which can reduce dependence on outside support for future releases.

What happened: - A leading Caribbean bank launched Phase 2 of its Temenos core banking transformation with Validata’s Agentic AI platform. - Phase 2 expanded the new core banking system to accounts and deposits. - The bank had already completed Phase 1 before this rollout. - The bank used Validata to automate end-to-end testing and data migration for the program. - Validata said the deployment delivered a smooth, efficient and lower-risk transition. - The bank is one of the region’s largest financial groups, with assets above $13 billion. - The institution is known for digital banking and financial innovation.

The details: - Validata’s platform uses agentic AI to generate, execute and maintain tests, detect defects, and support data transformation and reconciliation with limited human effort. - The system learns as banking applications change and identifies new test cases and risks across program phases. - Validata’s model-based approach creates a digital twin layer across core banking systems, digital channels and third-party applications. - The bank used a phased coexistence approach for data migration, structured in three distinct stages. - The migration setup included reconciliation, auditability, historical data preservation and governance controls. - The bank’s high-performance preparation capabilities enabled end-to-end migration automation. - The QA approach moved beyond standalone pre-launch testing to continuous software intelligence and continuous delivery. - Functional, regression and performance tests run with each release inside the bank’s CI/CD pipeline. - Testing now covers the core system and digital channels, including mobile banking, to validate customer journeys from app to core. - Validata’s integrated test data management and synthetic test data generation were part of the rollout. - The automated regression suite built in Phases 1 and 2 now belongs to the bank and is ready for future phases, upgrades and releases. - Phase 2 also coincided with the bank’s move from Temenos Navigator to the Temenos Explorer user interface. - Because the platform is model-driven, the bank reused existing business models instead of rebuilding test scripts from scratch. - After structured training and knowledge transfer from Validata, the bank’s QA team now designs, runs and maintains automated tests internally. - Validata remains a strategic partner to the bank.

Between the lines: - The rollout signals a shift from project-based testing to a reusable testing asset that can support later upgrades. - Reusing business models for the new user interface suggests the bank is trying to limit the cost and friction of future UI changes. - The move to internal ownership of QA points to a maturity step in the transformation program, not just a vendor-led implementation. - Validata is positioning agentic AI as a way to sustain banking transformation beyond the initial go-live.

What's next: - Validata said it expects to continue supporting the bank as the transformation advances. - The bank’s regression suite and model-based test assets are in place for future phases, updates and releases. - The company said the relationship is set up to handle the next core banking phase, a new interface or additional digital services. - Validata founder and CEO Vaios Vaitsis said the partnership is expected to drive further innovation together.

The bottom line: - The bank’s Phase 2 launch shows how agentic AI can be used to scale core banking change while keeping testing, migration and QA ownership under control.
