Validate Data Before the New System Goes Live
Tristha helps enterprises — from banks, insurers and payment providers to healthcare, retail and telecom — validate migrated data across records, mappings, transformations, relationships and downstream workflows before migration gaps reach production.
Legacy data quality debt
incomplete, duplicate, outdated or inconsistent records silently carry over into the modernised platform.
Mapping errors
source-to-target mapping mistakes corrupt customer records, account data, transaction history, policy details and reporting outputs.
Broken relationships
links between customers, accounts, products, transactions, claims and reference data fail in the target, breaking downstream processes.
Transformation failures
data is reformatted, reclassified, recalculated or truncated incorrectly during the move.
Cutover pressure
defects found in the final stretch are the most expensive and dangerous to fix; sampling-based checks miss them.
Late downstream impact
reports, reconciliations, servicing workflows and digital channels expose migration defects only after go-live.
Regulatory and audit exposure
migrated financial, customer and compliance data must remain traceable, reportable and audit-ready.
Problem
Why Data Migrations Fail Without Dedicated Testing
Our Offerings
Bridging Old and New
We test across legacy and modern systems together, validating integration points so upgrades and patches don't disrupt live operations.
Audit-Ready Compliance
Test coverage mapped to compliance requirements, with audit-ready documentation proving changes introduce zero regulatory gaps.
Precision on Business Logic
Rigorous testing of calculations, account rules, and workflows — because even small changes can break customer accounts and financial reporting.
Accuracy at Every Step
End-to-end validation of balances, calculations, settlements, and reports — catching discrepancies before they hit production.
Built for Scale
Testing under real transaction loads to confirm performance, scalability, and responsiveness hold up at scale.
Smart, Secure Test Data
Realistic, production-like test data — masked and anonymized to protect customer information without compromising coverage.
Build reusable regression suites
that protect critical BFSI functionality across releases, patches, upgrades and enhancements.
Prioritize high-risk test coverage
across transaction paths, regulatory workflows, integration points and revenue-impacting functions.
Execute regression cycles
to confirm that existing features continue to perform after application changes.
Optimize test packs
by removing redundancy, improving coverage and focusing effort on business-critical scenarios.
Identify automation-ready regression scenarios
for faster, repeatable and scalable release validation.
Deliver release-readiness insights
through test progress, defect trends, coverage status and go/no-go support.
Data Migration Testing Services
Migration test strategy and scoping
define entities, waves, mapping coverage, acceptance criteria and risk-based validation priorities.
Source data profiling
baseline data quality, counts and checksums before the first load, so target defects are never blamed on unknown source issues.
Source-to-target completeness validation
record counts, field-level comparison, missing and extra record identification across every migrated entity.
Transformation and business rule validation
formats, calculations, classifications, aggregations, conversions and enrichment logic applied during migration.
Referential integrity testing
relationships across customers, accounts, policies, cards, transactions, claims, products and reference data.
Reconciliation and exception reporting
duplicates, incomplete loads, mismatched values, null and default-value substitutions, with clear defect triage.
Mock migration and parallel-run validation
rehearsal loads and side-by-side comparison of legacy and target outputs before the business switches over.
Cutover and post-migration assurance
go/no-go readiness inputs, rollback validation support and hypercare checks after go-live.
Non-functional and compliance validation
load-window performance, data privacy and masking checks, and audit-trail traceability.
Validate business functionality
across onboarding, payments, cards, lending, deposits, insurance, servicing, reporting and back-office operations.
Design scenario-led test cases
increases as banks, insurers and financial platforms respond to regulatory, product and digital transformation demands
Test end-to-end workflows
across screens, APIs, integrations, data flows, downstream systems and customer-facing channels.
Verify business rules and calculations
for transaction accuracy, eligibility checks, fee logic, interest computation, claims rules and process outcomes.
Execute positive and negative test scenarios
to confirm expected behaviour across standard, alternate and exception conditions.
Report functional defects clearly
with severity, impact, reproduction steps and business context for faster resolution.
Why Tristha
Financial domain depth
we validate migration outcomes through the lens of customer, transaction, reporting and operational workflows, not just row counts.
Techno-functional QA
we connect technical data validation with business rules, process continuity and user readiness.
TraviS-powered automation
automated reconciliation, field-level comparison, schema checks and duplicate detection enable full-population validation instead of sampling, with CI/CD integration.
Mapping-led method
testing is anchored to documented source definitions, target expectations and transformation rules.
Reusable validation assets
repeatable checks accelerate every subsequent wave, parallel run and release cycle.
Release-readiness focus
stakeholders get clear, evidence-based visibility into migration gaps, defect impact and cutover readiness.
Find migration gaps before they become business process gaps.
Client Outcomes,
in Their Own Words
We sincerely appreciate the expertise and dedication demonstrated by Tristha & Finonyx in supporting our Performance Engineering and Test Automation efforts during the Flexcube 14.7 upgrade project. Their proactive approach, technical proficiency, and untiring commitment were instrumental in the success of this upgrade.
A key highlight was their exceptional performance engineering efforts, which covered all critical transactions across Flexcube Modules, OBBRN, APIs, ATMs, Mobile Applications and Other Application Interfaces. The team effectively simulated real-world production scenarios, generating various transaction loads within SLA-defined timeframes. This rigorous testing helped validate the application’s performance under actual operating conditions.
Additionally, TerrA’s capability to automate testing across various Flexcube 14.7 modules, including Web and APIs ensured comprehensive end-to-end test coverage for the base Flexcube modules. We also greatly appreciate the extensive training and dedicated support provided to the QA & Testing team and various Business Units/Teams on TerrA.
We are truly grateful for their contributions on this great Project Everest and looking forward to future collaborations.

We appreciate the support provided by Tristha & Ifinity in our Test Automation and Performance Engineering efforts during the Temenos T24 upgrade project. Their structured approach and technical expertise contributed to the overall execution of the upgrade. One key aspect was the ability of their automation platform ‘TerrA’ to support testing across multiple platforms, including web, mobile, APIs, databases, and file validations, enhancing test coverage. Additionally, their performance engineering efforts included testing critical transactions across T24, ATMs, and mobile applications. By simulating real-world transaction loads within SLA-defined parameters, they contributed to the validation of the application’s performance under operational conditions. We acknowledge their contributions to the project and appreciate the collaboration.

We had been constrained for months by our dependency on the switch and a rigid simulator that forced all test traffic through the switch layer. Working with Tristha’s SiPay simulator, we were able to bypass switch entirely and test directly against the core by building the required AS 2805 flows in SiPay, with no new code and no configuration changes to our environment, and this has now unlocked faster regression and far better reuse of our existing script automation assets.
