Insurance Legacy Modernization

Modernize insurance legacy applications and core platforms with cloud, data and AI to reduce technical debt, improve agility, and accelerate product launches.

Insurance legacy modernization enables carriers to move faster without compromising platform stability or operational resilience. When core policy, claims, billing and underwriting systems are burdened by technical debt, brittle integrations and rigid data models, even small product changes become slow, costly and disruptive, ultimately degrading customer and employee experiences.

Whether modernizing a single line of business or transforming the core enterprise platform, our approach is anchored in measurable business outcomes. We help insurers accelerate change cycles, reduce outages, increase straight through processing and deliver better experiences for policyholders and adjusters, while preserving regulatory compliance and day-to-day operational continuity.

Persistent modernizes insurance core systems through a pragmatic, fit-for-purpose strategy that includes rehosting, re-platforming, or refactoring, guided by deep architecture assessments, domain-led decomposition and API-first integration. Combined with infrastructure, cloud and database modernization, this creates a resilient and scalable foundation that improves performance, strengthens security and delivers greater cost transparency across environments.

We also modernize the data, infrastructure and operations landscape, moving from Legacy to modern RDBMS, consolidating siloed policy and claims data into a centralized enterprise data platform. Supported by ZeroL1 operations and AIOps, the result is a future-ready, modular architecture that reduces run costs by eliminating technical debt, accelerates product and digital channel launches and enables intelligent decisioning allowing carriers to continuously evolve without reintroducing legacy constraints.

FAQs

How does Persistent approach legacy core system modernization without disrupting daily insurance operations?

Persistent applies a pragmatic, fit-for-purpose strategy anchored in deep architecture assessments and domain-led decomposition to modernize core policy, claims and billing systems. This approach preserves regulatory compliance and day-to-day operational continuity while systematically reducing technical debt.

What role does GenAI-assisted engineering play in accelerating insurance mainframe modernization programs?

GenAI-assisted engineering accelerates modernization programs by approximately 25% through rapid code comprehension, automated testing and intelligent documentation. Persistent leverages this capability to transform legacy mainframe and core technologies into modern Java/.NET stacks while decomposing monoliths into modular, API-driven services. This approach reduces modernization risk and speeds delivery across complex insurance application portfolios.

How does Persistent help insurers migrate from monolithic cores to API-driven modular architectures?

Persistent decomposes monolithic insurance cores into modular, API-driven services using API-first integration principles and composable architecture patterns. This transformation accelerates release velocity by 30%–40% by decoupling legacy dependencies and enabling seamless integration between modernized components, legacy systems and COTS platforms. The resulting architecture allows carriers to evolve continuously without reintroducing legacy constraints.

What is Persistent's strategy for modernizing policy and claims data while maintaining regulatory compliance?

Persistent consolidates siloed policy and claims data into a centralized enterprise data platform while migrating from legacy to modern RDBMS. The approach delivers enhanced data quality and reduces turnaround times by 20–35% through real-time data pipelines that provide actionable insights across operations. This modernization maintains regulatory compliance throughout the transformation while improving platform stability and resilience.

How does Persistent determine whether to rehost, re-platform, or refactor legacy insurance applications?

Persistent conducts deep architecture assessments to determine the optimal modernization path, whether rehosting, re-platforming or refactoring, based on measurable business outcomes and technical debt analysis. This decision framework considers platform stability requirements, cost optimization targets and business agility goals.

What engagement models does Persistent offer for multi-year insurance core modernization transformations?

Persistent designs modernization programs anchored in measurable business outcomes, whether transforming a single line of business or the entire core enterprise platform. The approach combines domain-centric product engineering with AI-first capabilities to accelerate delivery and reduce risk. Engagement strategies prioritize operational continuity while systematically addressing technical debt across policy, claims, billing and underwriting systems.
