Modernizing the Backbone: Why Legacy Platforms Are Holding Back the Pensions and Retirement Industry

The U.S. pensions industry is standing at a crossroads. On one hand, demand for retirement solutions has never been greater, as an aging workforce looks for stability and younger participants demand transparency and digital access. On the other, many providers are weighed down by outdated, fragmented legacy platforms that were never built for today’s digital-first, hybrid environment.

This tension has created a perfect storm: aging infrastructure, rising operational costs, shifting participant expectations, and mounting regulatory pressures. For providers, modernization is no longer a nice-to-have, but is a business necessity that directly impacts competitiveness, risk management, and client trust.

The Cost and Risk of Legacy Systems

Legacy platforms in pensions and wealth management often date back decades, patched together through acquisitions, regulatory changes, or stopgap digital initiatives. While these systems may still function, they create hidden costs and risks:

  • Operational inefficiency: Manual processes, data duplication, and brittle integrations lead to delays and errors.

  • Security gaps: Older systems often lack the resilience and security features needed to meet modern cybersecurity standards.

  • Inflexibility: Adding new products or regulatory updates becomes a costly, time-consuming endeavor.

  • Client dissatisfaction: Participants accustomed to modern apps in other areas of life find legacy pension interfaces slow, outdated, and confusing.

    The result? Higher costs, lower agility, and a widening gap between what pension providers can deliver and what participants expect.

What “Modernization” Actually Means

The term modernization is often thrown around, but in practice it can mean very different approaches:

  • Lift-and-shift: Moving legacy systems to the cloud without addressing architectural limitations. This reduces infrastructure costs but often perpetuates inefficiencies.

  • Replatforming: Migrating to a modern, modular platform while preserving core business logic. This balances continuity with agility.

  • Greenfield build: Designing a completely new system from scratch, leveraging cloud-native architecture and modern frameworks. This is the most transformative but also the most complex path.

    The right strategy depends on business priorities, regulatory obligations, and risk appetite. What’s clear is that “doing nothing” is no longer viable.

Lessons from Successful Platform Transformations

Modernization isn’t easy, but done well, it delivers enormous benefits. Consider the experience of a global leader in wealth management, which provides a cloud-hosted registry for wealth managers, superannuation providers, and fund platforms.

Since 2008, Hengtian has partnered with this European client on large-scale initiatives spanning system re-engineering, migration, product R&D, and digital solution development. One landmark project involved re-engineering the client’s retirement planning platform, a mission-critical portal serving employers and employees.

Over 14 months, a 60-person Hengtian team delivered a redesigned architecture, improved stability, and a customizable interface that supported dynamic client needs.

Other initiatives included migrating legacy systems with minimal disruption, building innovative tools like the Mockserver to boost development efficiency, and developing a CMS Visual System that empowered users with easy customization. These efforts not only reduced operational costs but also transformed user experience and future-proofed the platform for global growth.

The key lesson? Modernization succeeds when technology expertise is paired with strategic ownership and proactive problem-solving. As one of the client’s project manager put it:

“Your team isn’t just blindly following specifications. You are thinking of the best way to implement the solution early in the development process before coding begins.”

This mindset – treating modernization as both a technical and business transformation – is what separates successful projects from failed ones.

Building for Long-Term Agility

True modernization isn’t just about today’s upgrades – it’s about building for tomorrow’s agility. That requires:

  • Cloud-native architecture: Ensuring scalability, resilience, and faster time-to-market.

  • Modular design: Enabling providers to add or adapt features without disrupting core operations.

  • Regulatory readiness: Designing systems flexible enough to meet evolving compliance requirements.

  • User-centric design: Creating intuitive, responsive interfaces that enhance participant engagement.

    By adopting these principles, pension platforms can move from being reactive and maintenance-heavy to becoming proactive, participant-focused systems that drive long-term growth.
