Migration from Mirth Connect to Open Integration Engine (OIE)

Maintain the Freedom of Open-Source Interoperability.

As Mirth® Connect transitions toward a proprietary, closed-source model (starting with version 4.6), many healthcare organizations face a critical crossroads: accept vendor lock-in and rising licensing costs, or seek a truly open-source alternative.

Meditecs: Expert OIE Migration Services

The Open Integration Engine (OIE) is the community-driven, vendor-neutral fork of Mirth® Connect. It preserves the familiar architecture you trust while ensuring your integration environment remains free, extensible, and community-governed.

At Meditecs, we provide expert migration services to help you transition your existing channels and infrastructure to OIE without downtime or data loss.

OIE is a direct fork. This means your existing JavaScript transformers, filters, and channel configurations are fully compatible.

Community Governance

Benefit from a roadmap driven by healthcare engineers, not corporate shareholders.

Security & Compliance

Access modern security updates, including TLS 1.3 and advanced encryption, without needing a “Premium” subscription.

Our OIE Migration Process

Migrating an integration engine is a mission-critical task. Meditecs follows a proven 4-step framework to ensure a risk-free transition.

Discovery & Inventory

We audit your current Mirth Connect environment, documenting every channel, global script, and database dependency.

OIE Environment Setup

We deploy a hardened Open Integration Engine instance optimized for your specific workload (Windows or Linux, on-premise or Cloud).

Channel Porting & Optimization

We migrate your channels to OIE, testing every transformation and destination. During this phase, we also optimize legacy code for better performance.

Zero downtime Go-Live

We run OIE in parallel with your existing engine to validate data integrity. Once verified, we execute a seamless cutover.

For Hospitals: Strategic Options After Mirth Connect Licensing Changes

Key risks identified

Budgetary: Unforeseen recurring license fees that were not part of annual budgets.
Operational: The risk of progressive obsolescence for those staying on old open-source versions without a clear roadmap.
Regulatory: Increased difficulty in justifying security patches during audits (e.g., ENS compliance).
Dependence: “Vendor lock-in” that reduces technological autonomy and limits future negotiation power.

Growing concern

Based on recent Meditecs research involving over 50 Spanish hospitals, the shift in Mirth® Connect licensing has created significant uncertainty.

Over 80% of hospitals surveyed expressed deep concern regarding licensing costs, security vulnerability support, and long-term maintenance.

Why Hospitals Choose OIE + Professional Support

This strategy allows hospitals to maintain the technical architecture they already know while upgrading their support structure.

Zero License Fees: Reinvest your budget into innovation rather than “per-connection” fees.
Independence: Maintain total control over your roadmap, independent of the original manufacturer.
Audit-Ready Security: Receive formal, documented support and updates aligned with modern standards like FHIR, EHDS, and ENS High-Level security.
Zero Technical Debt: Because OIE is a direct fork, your existing channels, JavaScript, and logic do not need to be rewritten.
