Sollers partnered once again with L’olivier Assurances to deliver a major Guidewire upgrade programme, covering core policy, billing, claims, and contact management systems.
The transformation spanned multiple markets and was delivered through a sequence of coordinated initiatives. Since 2024, the program has included three major projects: a claims system upgrade, a policy and billing systems upgrade, and ongoing development of new claims functionality. Each phase was executed with consistent governance and close collaboration, ensuring smooth delivery and a stable go live experience across all releases.
The successful delivery reinforced a long-standing collaboration and supported L’olivier’s continued growth in a highly competitive insurance market.

Challenge: Guidewire upgrade without disruption
L’olivier needed to upgrade multiple Guidewire platforms from version 8 to version 10 while simultaneously introducing new claims automation capabilities and maintaining business continuity.
The programme combined technical upgrades with functional enhancements, all delivered under tight time and budget constraints and across distributed teams in France, Spain, and Poland.
Key challenges included:
Limited time to gather and validate requirements
Parallel workstreams across multiple Guidewire products
Limited in-house knowledge of DARVA integrations
A large volume of test scenarios
Performance testing requirements to support sales growth
Data quality issues, including broken billing records
Compliance with data retention policy of Admiral group
Fast & trusted Guidewire® implementation partner
Helping P&C insurers around the world implement Guidewire solutions since 2011
Solution: phased Guidewire upgrade with governance
Sollers delivered through close collaboration, strong leadership, and deep Guidewire expertise, maintaining momentum from onsite delivery through to remote execution.
Guidewire upgrade scope: Policy, Billing and Contacts
We upgraded core systems to version 10, including:
PolicyCenter (PC) V8 → V10
BillingCenter (BC) V8 → V10
ContactManager (CM) V8 → V10
ClaimCenter functional upgrade
More than 3,000 test scenarios for PC/BC upgrade were executed to ensure stability and regression coverage across all systems.
ClaimCenter enhancements: IRSA/IRCA automation and DARVA integration
Claims processes were modernised through automation and platform-native functionality:
Enhancement of the IRSA process, including new features aligned with IRSA convention
Replacement of 30+ bot-based processes with Guidewire out-of-the-box automation capabilities
Integration of the IRCA process in ClaimCenter through integration with DARVA
Implementation of IRCA message handling
New features to automate bodily injury claim processing
Refactoring of some technical debt to allow for easier maintenance and development of the IRSA process
Data retention and compliance: purge processes and AWS document deletion
Sollers supported data retention and purge processes by:
Implementing claim purging mechanisms
Supporting monitoring teams during purge operations
Handling document deletion from AWS cloud storage
Why it worked: disciplined QA for the Guidewire upgrade
Leadership alignment and disciplined testing were key drivers of delivery quality throughout the programme. While the upgrades to the claims, policy, and billing systems stayed closely aligned with the original plan, the development of new claims functionalities (IRSA/IRCA) required more adaptive planning due to their evolving scope. Even with these adjustments, the programme maintained strong control and delivered stable, well-governed releases.
Sollers played a key role in the successful delivery of the Guidewire upgrade, taking full ownership of the programme from platform upgrades and claims process automation through to complex integrations, including DARVA IRCA integration. Through rigorous testing, quality assurance, and performance optimisation, the team ensured a smooth and reliable transition to production. Ongoing support during the warranty phase further reinforced system stability, helping the client start operations with confidence after go-live.
