Hospitals and life science labs run on massive amounts of data. But the systems holding patient histories, research, and billing are often decades old. In healthcare, you simply cannot afford downtime. If a medical system crashes, it affects real people, not just profits. Plus, keeping old mainframes secure and HIPAA-compliant gets harder every year as the original engineers retire.
Instead of taking the huge risk of swapping everything at once, smart hospital networks are moving piece by piece. This allows clinics to stay open while the background tech gets an upgrade. Here is a look at the best mainframe modernization companies helping the medical field safely update their legacy systems today.
1. Corsac Technologies
- Focus: Secure Healthcare IT Modernization
- Best For: Hospital networks and medical billing
Corsac Technologies tackles the delivery inertia that slows down medical networks. Hospital operations can’t pause for IT changes, so engineers work directly in existing Git repositories and CI/CD pipelines. They rebuild legacy systems into .NET Core microservices. In healthcare, security can’t be added later, so HIPAA and SOC2 are built into the architecture, reducing technical debt at the core. You can see how this approach works in practice in their mainframe modernization services
2. Refactorly App
- Focus: AI-Assisted Medical Data Extraction
- Best For: Legacy Electronic Health Records (EHR)
Refactorly App provides a solution for upgrading legacy healthcare systems with less risk. Manual rewrites of medical records are error-prone. It treats old code as structured data using RAG architecture and a multi-agent system. One agent scans EHR logic for risks, while AI generates updated code for review. A circuit breaker can revert traffic if issues appear, keeping sensitive data systems stable.
3. Astadia (Amdocs)
- Focus: Large-Scale Enterprise Migrations
- Best For: National health systems
Astadia maps out the entire move from the first code audit to the final cloud setup. Healthcare systems are usually a tangled mess of different tools bought over the years as hospitals merge. Astadia specializes in untangling this old code. They help large providers lift their current system to the cloud or completely rewrite it to improve portals for doctors and patients.
4. TmaxSoft (OpenFrame)
- Focus: Fast Infrastructure Shifts
- Best For: Cutting expensive hardware costs
TmaxSoft offers a fast escape route from expensive data centers. Their OpenFrame technology lets medical providers run old mainframe apps in the cloud without rewriting the actual code. This “rehosting” is a great choice for hospitals that need to cut hardware costs right away but aren’t ready to rebuild their core patient databases from scratch..
5. CloudFrame
- Focus: Gradual Workload Shifting
- Best For: Medical claims and billing batches
CloudFrame is perfect for health insurance companies dealing with massive daily claims. Their software turns old COBOL code into Java, letting it run on cheaper cloud servers while keeping the main database intact. This lowers monthly hardware bills instantly and allows medical providers to move specific heavy workloads step by step.
6. Advanced (Modern Systems)
- Focus: Code Translation and Assessment
- Best For: Strict hospital budgets
Advanced brings powerful automated tools. They convert old languages used in legacy pharmacy and lab systems into modern code. Before work begins, they provide a detailed report showing exactly what can be moved automatically and what requires manual work. This gives hospital boards a clear picture of the budget and timeline.
7. Rocket Software
- Focus: Data Connectivity and Hybrid IT
- Best For: Real-time data access in highly regulated labs
Rocket Software specializes in connecting legacy mainframes to modern cloud tools without moving the data itself. For healthcare labs that need to access old research records in real-time using new AI tools, this is a major advantage. They focus on automation and ensuring that old data can be used in modern mobile apps or portals. This “hybrid” approach is excellent for medical companies that want to keep their secure mainframe as a back-end while offering a modern experience to their staff and patients.
Final Thoughts
Updating a healthcare system is about providing better patient care, not just saving IT budget. The right partner helps a hospital stop fighting slow software and start focusing on people. The vendors listed here offer different ways to get there. Your choice depends on whether you need a fast move to cut costs or a full rewrite to build better digital tools. The ultimate goal is to turn a heavy technical burden into a flexible system that supports your medical staff.
