Coforge partnered with a Fortune 500 financial services organization managing $90B+ in assets to modernize its legacy policy administration landscape. The client operated multiple PAS systems across business lines, leading to high costs, operational complexity, and limited agility.

By adopting a Mainframe-as-a-Service model and leveraging agentic AI-driven migration and validation, Coforge enabled a controlled, scalable modernization. The transformation streamlined platform operations, reduced costs, and accelerated product innovation while ensuring continuity across millions of in-force policies.

The Challenge

The client’s technology landscape had become highly complex due to multiple mergers and acquisitions, resulting in six legacy PAS platforms supporting various product lines. Managing millions of in-force policies across these systems led to high operational and maintenance costs.

Complex product definitions, extensive historical data, and interdependencies across platforms further increased the difficulty of modernization. Rising infrastructure, licensing, and support costs added to the challenge, limiting the organization’s ability to invest in innovation.

The client required a structured modernization approach that could reduce costs, simplify the platform landscape, and enable faster product development without disrupting ongoing operations.

Our Approach

Next-Generation PAS Migration

Migrated legacy systems to a modern policy administration platform using a proprietary conversion framework designed for large-scale transformations.

Automated Data & Policy Conversion

Leveraged custom accelerators and tools to automate the transformation of policy data, reducing manual effort and ensuring accuracy.

AI-Assisted Testing & Validation

Implemented agentic AI to automate test creation, data validation, and reconciliation, improving quality and reducing migration risk.

Modern Product Configuration Enablement

Enabled advanced configuration capabilities to accelerate the definition and launch of new insurance products.

Mainframe-as-a-Service Model

Adopted a scalable operating model to optimize infrastructure utilization while maintaining continuity for legacy workloads during transition.
