Guidewire Cloud migration QA: passing quality gates faster

QA for Guidewire Cloud migration: a key to stay ahead in a demanding market

Jan 28, 2026 Guidewire , Case study , Cloud, Quality Assurance

The client was a Nordic insurance company offering a wide range of products for employment contracts. The organisation was (and still is) focused on remaining one of the most technologically advanced insurers in it’s region.

The insurer set out to migrate its full Guidewire suite – PolicyCenter (PC), BillingCenter (BC) and ClaimCenter (CC) – to the cloud. Given the 100+ integrations, limited prior cloud experience, and significant unit test debt, the biggest question was not “Can we migrate?” – it was “Can we migrate with confidence?”

Sollers supported the client by conducting a QA assessment and devising test strategy and supervision plan. With this support, the client passed cloud quality gates, reduced testing friction, and established a robust QA framework for the next phase of their technology roadmap. We also helped define a 2-year QA transformation roadmap for the team.

Complexity at scale – with no room for downtime

The migration programme combined significant platform-level changes and posed a high operational risk:

Full cloud migration of Guidewire PC, BC and CC
100+ integrations and complex end-to-end business journeys
Large technical debt in unit tests, which was blocking readiness and slowing delivery
Limited client experience with cloud delivery constraints
Test coverage gaps and duplicated/overlapping test cases
Inefficient test data management impacting execution speed
Utilisation of pre-existing test automation solution and scenarios

Turning QA into a repeatable capability

A comprehensive testing strategy for cloud migration

We developed a practical, end-to-end testing strategy for the migration programme, covering systems, integrations, critical and supporting transactions, and all key user types. The strategy didn’t stop at the go-live: it also included a 2-year improvement plan to ensure that QA remains scalable as the platform evolves.

QA assessment and maturity audit across 5 models

In order to make improvement measurable, we audited the testing area against 5 different models and mapped areas for improvement, prioritising changes that would reduce risk the fastest (in terms of coverage, test data, unit-test health, and governance).

Leading in incorporation of pre-existing test automation framework

This was one of the first implementations of BYOT (Bring Your Own Testing), combining the Guidewire cloud pipeline with a Python-based, pre-existing test automation framework to carry out designated functions tests as well as regression automated scenarios. This was critical in facilitating code promotion within quality gates.

Test suite optimisation

We ran QA reviews with the aim of reducing test case overlap, refining the scope, and improving ownership clarity, so that teams could work faster without compromising on coverage.

Security and performance testing guidance

Cloud readiness requires more than just functional checks. We provided guidance on security and performance tests to help build confidence in production-like behaviour before deployment.

Unit test stabilisation for PC, BC and CC

Technical debt in unit tests was a key blocker. We validated the quality of unit tests quality across all three Guidewire products and resolved the most critical issues to support cloud quality gates and ensure the reliability of releases.
