Introduction
Legacy system modernisation is now essential for insurers to thrive in today’s fast-paced industry, where frequent mergers and acquisitions demand growth and cost control to stay competitive.
However, many insurers are constrained by outdated legacy systems deeply woven into their daily operations. These systems, which manage critical functions like Policy/Claims Administration, Management Information (MI), Business Intelligence (BI), and Accounting, often act as roadblocks, stifling innovation and hindering growth.
It’s common to find Microsoft Excel and Outlook, the most widely used applications in these environments. Yet, it’s easy to forget that Excel was introduced in 1985 and Outlook in 1996. While these tools are user-friendly and widely adopted, they contribute to fragmented business processes and siloed data, preventing organisations from fully leveraging information to make better business decisions.
This reliance on outdated systems has led to “shadow IT” solutions—quick fixes that fill gaps in business processes but lack formal software development’s rigorous governance and controls. As a result, these patchwork solutions have led to inconsistent processes and business rules across the organisation, making it even more challenging to transition to modern systems.
In this blog post, we’ll explore the challenges of updating legacy systems and share two contrasting approaches to modernisation that demonstrate how to overcome these obstacles effectively.

A Word on DORA
The Digital Operational Resilience Act (DORA), effective from January 2025, mandates that financial entities in the EU establish robust frameworks for managing IT risks, including detailed incident response plans and regular testing of digital resilience.
Entities must also ensure effective governance and oversight of IT risk management, integrate third-party risk strategies, and encourage information sharing on cyber threats within the industry. These regulations are designed to secure financial systems against disruptions, enforce stringent compliance and reporting requirements, and ensure seamless integration and resilience of digital operations across the sector.
Insurers with legacy IT systems face significant challenges in complying with DORA. These outdated systems often lack the advanced security features and flexibility required to meet DORA’s stringent cybersecurity, incident response, and reporting standards.
Integrating legacy systems with modern technologies and third-party services is complex, complicating the seamless data exchange for robust risk management. Additionally, these older platforms need help with scalability and performance under continuous monitoring and rigorous testing mandates.
PART II
Exploring Modernisation Approaches
Before embarking on a modernisation journey, evaluating the existing systems and exploring the available modernisation options is crucial. These can range from complete system overhauls to more nuanced approaches like adding modern layers over legacy systems.
Transforming legacy IT systems is a significant undertaking for insurance companies. It requires careful planning and execution to ensure the new systems meet modern standards while minimising disruptions.
Two primary approaches can be adopted for this transformation:
1. Full Replacement
A full system replacement, often called a “rip-and-replace” approach, involves completely discarding the legacy system and implementing a modern solution. This strategy is typically pursued when the existing system can no longer meet the evolving needs of the business or has become too expensive to maintain and update.
One option for full replacement is greenfield development, which involves building a completely new system from the ground up. This allows businesses to tailor the system to meet current and future requirements, leveraging the latest technologies and best practices to optimise the new solution for performance and scalability.
Another common approach is to adopt Commercial Off-The-Shelf (COTS) software. These ready-made solutions can be customised to fit specific business needs and offer the advantage of significantly reducing development time compared to building a system from scratch. COTS software balances rapid deployment and flexibility, making it an appealing choice for many organisations.
For businesses looking for scalability, flexibility, and cost-efficiency, migrating to cloud-based solutions is often the most attractive option. Cloud platforms can scale resources on demand, making them ideal for supporting modern digital capabilities while minimising operational costs. Cloud migration also opens the door to enhanced collaboration, data accessibility, and future-proofing through regular updates and security enhancements.
Finally, a hybrid solution can offer the best of both worlds by combining in-house development with COTS or cloud-based technologies. This approach provides the customisability and adaptability needed to ensure the system can evolve alongside business requirements while benefiting from the efficiency and flexibility of pre-built or cloud solutions.

2. Incremental Modernisation
Incremental modernisation is a step-by-step approach to upgrading legacy systems without needing a complete replacement. By gradually improving different components, businesses can enhance their systems while minimising the risks and disruptions that a full replacement might cause. This method allows organisations to continue their daily operations seamlessly, making it a more manageable and cost-effective strategy.
One effective strategy is Service-Oriented Architecture (SOA), which involves breaking down the legacy system into smaller, independent services. Each service is modernised and integrated with others using standardised communication protocols. This enables the system to function as a cohesive unit while updating individual components.
Another method is API enablement, where the existing system’s functionalities are exposed through Application Programming Interfaces (APIs). By allowing newer applications to interact with the legacy system via APIs, businesses can extend the system’s life and capabilities without a complete overhaul, making it easier to integrate with modern platforms.
The microservices architecture takes a similar modular approach but decomposes the legacy system into even smaller, independently deployable services. These microservices can be developed, deployed, and scaled individually, providing the flexibility to continuously add new features or enhancements without disrupting the entire system.
Refactoring is another technique that focuses on improving the structure and performance of the legacy system’s code without changing its external behaviour. By refining the existing codebase, businesses can make the system more efficient and easier to maintain over time, allowing for smoother upgrades and better performance.
Finally, data migration involves transferring data from outdated systems to newer, more modern ones. This process is often done in phases to ensure the integrity of the data and minimise disruption to business operations, providing a clear pathway to improved data management and system functionality.
Advantages

Technical Debt
Some legacy issues may persist and require future attention.
3. Choosing the Right Approach
Deciding between incremental modernisation and full system replacement depends on several critical factors, including the current condition of the legacy system, budget limitations, risk tolerance, and the business’s specific needs. Many companies find that a hybrid approach, which combines elements of both strategies, allows them to balance risk and reward more effectively.
Incremental modernisation is often preferred when the existing system still fulfils most business needs. This approach minimises disruption to daily operations and spreads costs over time, making it a practical and budget-friendly option for organisations with budget constraints or those seeking a gradual transition. It’s a strategy that allows for a smooth transition without overwhelming the budget.
The choice between incremental modernisation and full replacement depends on system condition, budget, and business needs. A hybrid approach often effectively balances risk and reward.
In contrast, full system replacement is chosen when the legacy system can no longer support modern business processes. This option particularly appeals to companies looking to lower long-term maintenance costs or implement a system with entirely new capabilities. A complete overhaul provides a fresh start and ensures the organisation is equipped to meet future demands, although it typically involves more upfront investment and operational disruption.
Ultimately, the decision between incremental modernisation and full replacement should be guided by the company’s specific goals, financial realities, and risk appetite. The right choice will balance innovation and maintaining operational continuity, ensuring it aligns with the company’s needs. This alignment is crucial in ensuring the chosen strategy effectively addresses the company’s challenges and opportunities.
