Optimising Migration from Legacy Treasury System to Calypso for a Leading UAE Bank

Industry & Segment

Capital Markets

Objective

One of the leading banks in the UAE wanted to ensure a seamless treasury transformation. The project involved replacing the bank’s legacy integrated treasury and risk management application system with application Calypso V 17 by Nasdaq system integration testing (SIT), performance testing (PT), user acceptance testing (UAT), and regression testing. We were able to deliver a defect-free experience post-go-live, unlocking the full potential of the new treasury management system.

Client Overview

The client is one of the largest private banks in the UAE, recognized for its innovative retail and commercial banking services. With a focus on digital transformation, the bank embarked on a treasury modernization journey to improve operational efficiency, reduce costs, and enable real-time risk monitoring. The transformation was aimed to support Seven highly trades products (Fixed Income, Repo, Money Markets, FX, FX Options, Interest Rate Swaps and Collateral Management) with higher degree of straight through processing and near real-time risk management.

Business Challenges

Legacy application limitations

The outdated system blocked business growth, restricted client offerings, high-volume processing, and near real-time risk assessment.

Complex requirement mapping

The bank received documentation from diverse user communities and needed to map them to business processes with the target treasury application.

External dependency

The bank relied heavily on 3rd party service partners, requiring seamless coordination to execute end-to-end processes in a timely manner.

Transform your treasury with confidence. Let QualityKiosk lead your migration success.

Solution Overview

QualityKiosk implemented a comprehensive transformation assurance program to support the bank’s migration from the legacy treasury platform to Calypso v17, ensuring a seamless transition across functional, integration, and performance layers.
The approach combined deep domain expertise, strong stakeholder collaboration, and a structured testing framework to unlock the full potential of the new treasury management system.

  • Stakeholder Alignment:

    QualityKiosk conducted detailed walkthrough sessions with business teams to align application functionalities with test cases, ensuring clarity and shared understanding across all parties.

  •  Comprehensive Test Case Development

    The team developed 5,000+ test cases for each testing cycle, achieving 100% coverage for BAU scenarios and ensuring thorough validation across all treasury products.

  • Automation-first Approach:

    An automation-first strategy was adopted early in the project. Automation scripts for critical functionalities enabled smooth execution during multiple UAT rounds and regression cycles.

  • Integration Testing Across Systems

    Close coordination with upstream and downstream application owners and third-party providers like Clearstream and Euroclear enabled robust end-to-end integration validation.

  • Structured Progress Tracking

    Day-wise execution plans were created and shared with stakeholders. Daily defect triage ensured timely prioritization and closure of issues.

  • End-to-End Performance Testing

    A detailed performance testing strategy validated system behavior across Calypso, EOD batches and EPH, BPS, Swift, and other connected applications. Simulated real-world user concurrency ensured reliable performance for end users.

  • Multi-Layered Monitoring

    A combination of tools such as AppDynamics, database logs, and Perfmon provided real-time visibility into application and system performance, enabling quick issue identification.

  • Performance Benchmarking & Tool Innovation

    Because Calypso is a thick-client application, traditional PT tools were insufficient. The team innovatively repurposed automation scripts and executed them using LoadRunner, supported by 20 terminals running LoadRunner and UFT for accurate load simulation.

Validation Strategy for Treasury Transformation (Legacy Treasury System to Calypso V17)

System Integration Testing (SIT)
Validated end‑to‑end workflows across Calypso and interfacing applications, identifying system defects early in the lifecycle.
User Acceptance Testing (UAT)
Enabled business teams to validate real‑world workflows, ensuring functional alignment with operational needs and confirming readiness for production use.
Regression Testing
Regression cycles were powered by the extensive automated test suite (5,000+ cases), ensuring that repeated changes did not break existing functionality.
Performance Testing Strategy
A tailored performance testing strategy validated Calypso V17 and all integrated systems by simulating real‑world workloads using LoadRunner, UFT, and JMeter, ensuring seamless end‑to‑end performance across Calypso, EOD batches, EPH, BPS, and Swift. A multi‑layered monitoring setup with AppDynamics, database logs, and Perfmon enabled precise issue detection and confirmed the platform’s readiness for high‑volume treasury operations.
Multi‑Layer Monitoring & Analysis
Real-time and backend monitoring tools helped validate resource usage, latency, transaction behavior, and integration health under stress.
