Customer Challenge Solution Results

This leading bank on the island nation of Mauritius has a growing international presence with ambitious plans for strategic expansion, embarking on an upgrade of their core IT systems.

Numerous obstacles related to timeline, reconciliation, version control, high number of defects, delays, and large data files were encountered during the data migration process.

Collaborating with the bank’s IT team and data migration partner, the Quinnox team developed a plan to perform data and financial recon-ciliation to ensure system upgrade success.

Reconciliation of all applications was done ahead of the data migration and cutover timelines for two locations; in some cases, migration delays were salvaged and the deadline met.

A leading bank in the Indian Ocean looks to Quinnox to execute on data migration testing as part of a move to a new core system.

Data Migration Reconciliation a Crucial Step in Bank’s Transformation

Major data migration project hinges on independent reconciliation validation

Quinnox team takes on challenges with expertise, rapid response, and proprietary tools

Based in the affluent Indian Ocean island of Mauritius, a leading financial services group was embarking on a major IT core system upgrade, dubbed project “Flamingo.” The project goals focused on leveraging new technologies to greatly improve customer service, operations, competitiveness, and risk mitigation. Ultimately, the aim was to elevate core banking functions to make great strides in four key areas – business, operations, service and technology.

This important and complex undertaking included crucial data migration from 16 legacy appli-cations to the new systems. But, to ensure success, the bank needed to perform independent data migration testing, or reconciliation validation. Done correctly, this would validate the correctness of migration by a third-party vendor, and meet target application requirements. Staying within the project budget was also a priority.

Reconciliation validation would need to include:

Our team was already part of a multi-phase Flamingo effort, so it was a natural choice for the bank to choose Quinnox to perform vital reconciliation validation. Because of the complexity of the data migration, as well as obstacles presented by a third-party vendor, the team had to overcome a number of significant and immediate challenges.

Reconciliation upstream applications came with an aggressive completion timeline to ensure go-live – within 18 hours of receiving the target data. This included all activities – data import, data transformation and comparison, defect analysis, and defect triage with the bank and system integrator. The complexity and volume of data was also a difficulty – some tables were as large as 30GB with over 50 million records. Missteps in version control, a high number of defects, unanticipated delays, and missing tables from data dumps received from target systems added to the challenges.

Fortunately, the Quinnox team was well-equipped to overcome all these obstacles. Even those that were unanticipated were addressed “on the fly,” ensuring Flamingo would fly on track. For example, a rapid response team was routed to a third-party vendor to quickly remediate issues and correct errors.

• Extraction of data from legacy systems

• Grouping of data into multiple entities, application-wise

• Transformation of data per business logic

• Comparison to target data

• Triage of data differences across mock migration cycles

Reconciliation validation delivered on time, providing high confidence to go forward

In addition, a variety of proprietary Quinnox tools and accelerators were used that helped over-come obstacles and add value, including:

Automated Source data and Extraction Tool – executed SQL script by priority and metadata, helping to rapidly extract data and execute precision uploads to targets

Quinnox Automated Comparison Tool® – compared the data element values between trans-formed source (expected result) and target, with differences written to a results table

Defect Upload Utility – Used to read the incidents from the migration results table and create an Excel® file in the QC upload-able format

Automated Product to GL Reconciliation Tool – extracted and transformed dynamic financial data from source applications, identified defects through mismatches, and generated GL adjust-ment entries to be made in the target

Best of all, the timely and efficient reconciliation validation services performed by the Quinnox team gave the bank’s IT team high confidence in their critical data migration. It was a necessary and vital step in moving Flamingo forward, and manifesting this growing bank’s core IT system transformation goals.

Data complexity, very large files, third-party missteps and delays, and other unexpected varia-bles were swiftly dealt with by an expert team using powerful Quinnox tools, resulting in:

Benefits by the numbers:
