Legacy System Modernization for a Healthcare Manufacturer

Modernizing a UniData-Based Platform Without Disrupting Operations

A global healthcare manufacturer partnered with Art+Logic to modernize a mission-critical system built on a UniData, multi-value database – an older technology still widely used in long-lived enterprise environments.

The system powered order management, inventory, and production. But as the business grew, it struggled to support:



Real-time inventory



Modern integrations



Scalable architecture

Art+Logic was brought in to modernize the platform—without interrupting daily operations.

The Challenge

Real-Time Requirements Meet Legacy Constraints

The client’s system presented a familiar, but formidable, set of legacy challenges:

Outdated architecture with minimal documentation
Critical business logic embedded in institutional knowledge
Inconsistent system behavior across regions
No reliable real-time inventory capabilities

At the same time, the business depended on highly configurable medical products, where inventory availability had to be precise to avoid ordering conflicts.

A full system replacement wasn’t feasible.

The new system had to coexist with the old one.

The Solution

Incremental Modernization That Works in Practice

Art+Logic designed a pragmatic modernization strategy focused on progress without disruption. Key elements included:

A new application layer integrating directly with the legacy database
A cloud-based data model to support scalability and future migration
Cross-system inventory coordination to prevent conflicts
Continuous adaptation as hidden system behaviors emerged

This approach enabled the client to move forward incrementally, reducing risk while building toward a modern architecture.

.

The Turning Point

Enterprise Strategy Shift

Midway through the project, the organization made a broader technology decision:

Transition from UniData to a modern ERP platform
Engage a large systems integrator to lead the transformation

Because Art+Logic had already mapped key system behaviors and dependencies, the client entered this transition with critical insights that reduced risk and uncertainty.

Results

Reducing Risk, Enabling Transformation

Even as the initiative evolved, Art+Logic delivered meaningful, lasting outcomes:

Lower migration risk by uncovering hidden dependencies early
Faster future development with a modernized data and integration foundation
Improved system visibility across legacy workflows
Continuity of knowledge supporting downstream teams and vendors

The work helped transform a high-risk modernization effort into a more informed, manageable transition.

AI + Legacy Modernization

Where It Adds Value

AI is increasingly part of legacy modernization, but its role is often misunderstood. In this project, AI could have:

Accelerated code analysis and documentation
Assisted with understanding legacy technologies
Supported data transformation efforts

But it could not:

Reconstruct undocumented business logic
Replace stakeholder expertise
Fully modernize a system of this complexity on its own

AI works best as a force multiplier, not a replacement for experienced engineering.

Why Art+Logic

Art+Logic specializes in complex legacy system modernization, helping organizations:

Extend the life of critical systems

Transition safely to modern platforms

Navigate uncertainty with confidence
