In an industry where reliability and trust are paramount, change doesn’t come easily. Insurance companies have spent decades building and refining their core systems—policy, billing, claims—all meticulously tailored to their operations. But in 2025 digital expectations from policyholders, agents, and even regulators are evolving faster than legacy systems can keep up. The result? A growing digital disconnect.

Insurers know they need to modernize, but a full system rip-and-replace is often too risky, too expensive, or simply not feasible. That’s where a Digital Experience Platform (DXP) comes into play. When implemented strategically, a DXP can help bridge the gap between legacy systems and modern digital demands—without disrupting the operational foundation that keeps the business running.

In this post, we’ll explore how insurance leaders can integrate a DXP into existing core systems to unlock agility, enhance customer experience, and accelerate transformation with confidence.

The Pressure of Legacy Systems on Modernization

Legacy insurance core systems have been battle-tested over decades. They’re reliable, but they weren’t designed for speed or omnichannel customer experiences. Most can’t support real-time personalization, integrate easily with mobile apps, or adapt quickly to new distribution models.

This technical rigidity creates real business consequences:

  • Long development cycles for new products.
  • Fragmented data across silos.
  • Poor digital self-service experiences.
  • High IT maintenance costs.
  • Inability to meet rising customer expectations.

These challenges represent more than an IT issue—they’re strategic blockers to growth, competitiveness, and customer satisfaction. Yet for many insurers, core system replacement remains impractical. A smarter solution is to extend what works and modernize what’s missing.

Enter the DXP: A Strategic Layer, Not a Replacement

A Digital Experience Platform (DXP) offers a powerful alternative to full system overhaul. In essence, a DXP acts as an orchestration layer—unifying customer-facing experiences across web, mobile, and portals, while integrating with existing backend systems through APIs or middleware.

While traditional CMS platforms focus narrowly on content management, a DXP is designed to orchestrate the entire digital journey—connecting content, data, and user interactions across channels. A DXP:

  • Personalizes experiences based on user behavior or profile data.
  • Connects multiple data sources (CRM, claims, policy, billing).
  • Supports omnichannel delivery with consistent UI/UX.
  • Provides analytics for optimizing digital engagement.
  • Enables composable, modular expansion over time.

Most importantly, a DXP doesn’t require replacing the core. It layers on top, offering a modern interface that draws data and capabilities from existing systems. Think of it as an experience layer that transforms what users see and do without touching the operational plumbing underneath.

This makes a DXP the ideal “bridge” for insurers looking to future-proof operations while preserving the stability of their legacy investments.

Why Insurers Are Turning to DXPs

Digital Experience Platforms directly solve key pain points in the insurance sector. They enable:

  • Faster Time to Market – Launch new products or experiences in months using low-code tools.
  • Omnichannel Consistency – Deliver unified customer experiences across mobile apps, web portals, agent tools, and more.
  • Customer-Centric Design – Personalize journeys to increase satisfaction and retention.
  • Data Integration – Unlock legacy data for real-time decision-making and personalization.
  • Incremental Modernization – Modernize in phases without compromising business continuity.

These outcomes aren’t aspirational—they’re already being realized by insurers who’ve adopted this model. A DXP is proving to be more than a technology play; it’s a business enabler.

How to Integrate a DXP with Legacy Insurance Systems

DXP integration isn’t a massive transformation overnight but a series of deliberate, strategic steps. Rather than disrupting core operations with high-risk overhauls, insurers can use a DXP to modernize gradually—building digital experiences on top of existing systems and scaling as business needs evolve. It’s a pragmatic path to transformation that balances innovation with operational stability. Here’s how to approach it:

1. Assess the Landscape

Evaluate your current systems and data infrastructure. Identify key integration points, understand data silos, and determine which digital touchpoints will benefit most from a modern experience layer.

2. Choose a Composable, API-First DXP

Select a platform that supports RESTful APIs, microservices, and flexible integrations. The right DXP should connect seamlessly to existing policy, billing, and claims systems without heavy customization.

3. Start Small, Then Scale

Begin with a high-impact but low-risk digital journey like a customer self-service portal or agent dashboard. Validate performance, gather feedback, and scale gradually to other parts of the business.

4. Leverage Middleware Where Needed

If your core systems lack modern interfaces, middleware can act as a translator, bridging the gap between legacy data formats and your DXP’s flexible front end.

5. Focus on Data Consistency

Ensure data flows reliably between the DXP and core systems. Define your source of truth (often the core), and avoid duplication or fragmentation. Real-time syncing or controlled batch updates can help maintain integrity.

6. Prioritize Governance and Change Management

Bring business and operations teams into the process early. Clear communication, training, and cross-functional ownership will accelerate adoption and reduce resistance.

Why This Approach Works

Integrating a DXP with legacy systems delivers measurable results while minimizing risk:

  • Maintains stability – Core systems remain intact.
  • Speeds innovation – Digital features can launch quickly.
  • Preserves investment – Extends the life of legacy platforms.
  • Improves customer experience – Enables modern, omnichannel interactions.
  • Builds future-readiness – Creates a flexible, scalable foundation for emerging technologies.

In short, the DXP becomes a strategic interface between yesterday’s systems and tomorrow’s expectations.

Final Thoughts

Optimization doesn’t always mean starting from scratch. Often the smarter path is building on what already works, using tools that can modernize experiences without disrupting core operations.

A Digital Experience Platform offers insurers a future-focused, customer-driven way to do just that. By layering innovation on top of reliability, insurance leaders can move quickly, serve smarter, and deliver the kind of seamless digital experiences today’s market demands.
