Case Study
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- Outdated architecture with minimal documentation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
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
- 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.
Supporting clinical software alongside legacy modernization The broader engagement also included Software as a Medical Device (SaMD) functionality supporting clinical planning. That work involved patient-centered workflows, presentation of planning information to clinicians, and architectural separation of regulated functionality from the surrounding application. Art+Logic worked with the client’s in-house compliance team and prepared documentation to support its regulatory process.
This clinical scope adds an important dimension to the modernization story. Business operations and clinical workflows can depend on connected systems, but they serve different purposes. Modernizing the surrounding application requires understanding which functions support clinical decisions, how information moves between components, and where a change could affect behavior that matters to users.
For medical software teams, the lesson is to define those boundaries before deciding what to replace. An incremental modernization plan should address both the legacy integrations that keep operations running and the distinct engineering and review needs of the clinical functionality. The client’s quality and regulatory responsibilities remain part of that planning; a framework upgrade alone does not resolve them.
AI + Legacy Modernization
Where It Adds Value
Those outputs still need review. Code alone may not explain why a business rule exists or whether current behavior is correct. Engineers must test assumptions and work with stakeholders to confirm the behavior the modernized system needs to preserve. AI assistance does not replace that responsibility.
