a.s.r.

Business objective

Following the acquisition of Aegon Netherlands in 2023, a.s.r. became one of the largest insurers in the Netherlands. The acquisition created an important strategic decision for a.s.r. to continue the policy administration across multiple legacy systems or consolidate the portfolio onto a future-proof policy administration system.

a.s.r. had already selected Keylane LeanApps Life as its target platform for individual life insurance administration. The next objective was to migrate more than half a million Aegon policies from three legacy back-office systems into LeanApps Life within 24 months.

Solution

a.s.r., Cegeka and Keylane worked closely together to deliver a large-scale migration project using the Keylane Migration Factory.

The migration project started in 2024. Within a few months, the first group of policies was successfully migrated, creating a proven approach for the remaining migration waves. By May 2025, the next 330,000 policies were migrated to LeanApps Life, followed by the final 225,000 policies in November.

The portfolio included complex products from different legacy environments, each with its own product structures, rules and administration logic. To manage this complexity, the migration combined product rationalisation, targeted software enhancements, and above all extensive product configuration.

A key enabler was the flexibility and high configurability of the LeanApps Life platform. Many of the portfolio’s complexities could be absorbed through configuration, making it possible to migrate policies from multiple legacy systems into several new, and mostly existing, a.s.r. products in LeanApps Life.

Throughout the project, the teams maintained a strong focus on delivery discipline, quality and aftercare. This helped ensure continuity while meeting the ambitious migration deadlines.

Business value

With all Aegon policies successfully migrated, a.s.r. has reached a major consolidation milestone: 1 million individual life policies are now administered in LeanApps Life, more than doubling the original policy volume on the platform.

The key business values include:

• Centralised policy administration by consolidating Aegon policies from three legacy systems onto one modern platform, reducing system complexity, improving maintainability, and simplifying day-to-day operations.
• Migration of more than 500,000 policies within 24 months, allowing a.s.r. to realise the benefits of consolidation within a defined timeframe while maintaining focus on business continuity.
• Scalable administration foundation, with LeanApps Life now supporting 1 million individual life policies for a.s.r. , giving the organisation a stable platform for high-volume administration and future portfolio growth.
• Stronger foundation for continued transformation, enabling a.s.r. to further modernise its life insurance operations, reduce dependency on legacy environments and focus more strongly on its core insurance business.

The project also reflects strong collaboration between a.s.r., Cegeka and Keylane, with Keylane acting as a strategic technology partner for complex migrations and future-proof policy administration.
