Novant Health operates an integrated network of 900+ medical facilities, providing seamless and personalized healthcare for communities across North Carolina and South Carolina. As the organization evolved, its 30-year-old legacy Cloverleaf engine — deeply embedded in everything from bedside care to back-office administration — reached its functional limits. Driven by the mounting risks of a 30-year-old foundation that lacked the cloud-native resilience and modern DevOps capabilities required for today’s healthcare demands, Novant Health realized strategic modernization was essential.
The Challenge: Replacing a 30-Year Foundational Legacy
Cloverleaf, the legacy system for Novant Health, was an infrastructure veteran that had been in service at Novant Health for over 30 years. For three decades, the platform became deeply woven into the fabric of the organization, serving as the silent backbone for thousands of daily clinical and operational data exchanges that caregivers, staff, and patients relied upon. Replacing such a deeply entrenched legacy system meant untangling decades of custom logic without snapping any vital threads.
The Legacy Burden
The complexity of Novant’s existing environment meant that the legacy system provided a critical, yet increasingly fragile service:
- Massive Integration Footprint: The platform governed a sprawling landscape of interfaces, facilitating thousands of critical clinical data exchanges daily.
- Deep Workflow Dependency: Cloverleaf was inextricably linked to staff’s ability to receive lab results, process pharmacy orders, and manage patient movement across the enterprise.
- Technical Obsolescence: After 30 years, the system had become a primary source of system obsolescence. It lacked the cloud-native resilience and modern DevOps capabilities required to support contemporary health-tech demands.
Safeguarding Patient Care and System Stability
The primary risk at stake was the potential for clinical disruption. Since the engine powered critical patient care workflows, any downtime, dropped messages, or misconfigured translations during the transition directly threatened continuity of care, daily organizational reliability, and system stability across the entire regional network. Downstream clinical systems had to experience zero disruption, requiring the new cloud-based engine to execute a “faithful reproduction” of the legacy logic.
To navigate these risks, Novant Health engaged J2 Interactive to lead a unique hybrid delivery model designed to ensure a seamless transition over a multi-year modernization timeline.
The Solution: A Hybrid Model for Strategic Transformation
Recognizing the mission-critical nature of the project, Novant Health strategically adopted a hybrid team approach that integrated the specialized expertise of J2 Interactive and internal Novant staff. This was a deliberate strategic choice: the goal was not just a technical cutover, but the cultivation of internal expertise and long-term self-sufficiency. By working alongside J2, Novant’s internal teams gained the mastery necessary to manage the platform independently, ensuring the investment provides value long after the initial migration.
Technical Architecture & DevOps
J2 architected a cloud-based environment focused on high availability and engineering excellence:
- Environment Configuration: J2 established robust Development, Test, and Production environments within Health Connect Cloud, featuring a configured failover to a second physical server to guarantee enterprise-grade resilience.
- Modern DevOps Integration: To eliminate manual legacy processes, J2 implemented Git-based source control. This enabled modern versioning, CI/CD patterns, and a disciplined development lifecycle that was impossible on the 30-year-old engine.
- Security Protocols: J2 directed the implementation of comprehensive user access and security groups across all environments, protecting sensitive clinical data within the cloud-first architecture.
Validation & Training
To eliminate the risk of clinical disruption, J2 utilized automated tools to compare Health Connect output directly against legacy Cloverleaf traffic. This ensured downstream systems received data with absolute parity. Simultaneously, J2 provided hands-on mentoring to the hybrid team, transitioning from consultants to educators to prepare the organization for the July 2026 completion.
The Results: Monumental Success and a Future-Ready Foundation
The project reached its successful culmination in July 2026, when all the interfaces went live on the InterSystems Health Connect platform with zero disruption to clinical care. This seamless cutover ensured that caregivers and patients remained unaffected by one of the most significant technology transformations in the organization’s history.
“The benefits of this achievement extend far beyond technology. This new platform strengthens reliability and resiliency, improves scalability, enhances our ability to innovate, and provides a stronger foundation for future growth. Most importantly, it supports our mission by ensuring the dependable flow of information that caregivers rely upon to deliver remarkable patient care every day.”

Strategic Outcomes
This transformation has shifted Novant Health from a position of reactive maintenance to one of proactive innovation:
- Strengthened Reliability and Resiliency: The failover architecture and cloud-native stability protect the organization from the downtimes associated with legacy hardware.
- Enhanced Scalability and Speed-to-Market: The standardized platform allows Novant Health to rapidly integrate new facilities. The success of the project serves as immediate proof of the platform’s ability to handle new, high-priority initiatives with speed and agility.
- Innovation Capability: By adopting InterSystems Health Connect Cloud, Novant Health now possesses the modern foundation required for advanced health-tech advancements, including real-time analytics and API-led interoperability.
This extraordinary accomplishment proves that Novant Health is no longer burdened by the legacy limitations of the past. By successfully navigating this 30-year modernization, the organization has demonstrated the power of Together — a core Novant organizational value. Through the coordination of IT, clinical, and business stakeholders, Novant Health has not only modernized its core backbone but has secured its future as a leader in cloud-first interoperability.
