Healthcare and life sciences have a mainframe problem that banking doesn’t. A calculation error in a banking system costs money. A calculation error in a system that manages patient records, clinical trial data, or pharmaceutical supply chains can cost something else entirely.
The regulatory environment reflects that. HIPAA, FDA 21 CFR Part 11, GDPR for patient data, GxP requirements for life sciences — these apply to every step of the modernization process, not just the end state. Every decision needs documentation. Every change needs an audit trail. Regulators don’t care how good the engineering was if the paperwork doesn’t hold up.
Before you start evaluating anyone, Recode is worth checking — a platform for finding and comparing companies in software modernization, application migration, and legacy transformation.
1. Corsac Technologies
Contents
Website: corsactech.com
Location: United States
Founded: 2007
Team size: 50-249
Corsac Technologies has a way to update old computer systems using artificial intelligence. This helps them understand how the systems work, find out what depends on what, and figure out the business rules that are hidden inside. They are especially good at doing this in the healthcare and life sciences fields, where there are a lot of rules to follow. Old healthcare computer systems have a lot of important information stored in them, like how to manage patient records, calculate bills, and report to the government. These rules were written a long time ago and were never fully written down because the systems just kept working anyway.
Corsac’s RAG architecture looks at the codebase in a more meaningful way, finding connections between different parts that actually work together, rather than just looking at what’s written down. The Multi-Agent Swarm identifies dependencies, spots potential security risks, and extracts the underlying business logic all at the same time. When it comes to healthcare, organizations need to make sure they’re meeting strict compliance requirements like HIPAA and SOC 2 Type II before they can work with patient data systems. The system checks for behavioral parity at every step of the re-engineering process, making sure that clinical calculations and reporting logic work exactly the same way in the new system as they did in the old one.

2. Reliqsy
Website: reliqsy.com
Location: United States
Founded: 2014
Reliqsy uses a combination of artificial intelligence and expert knowledge to update old healthcare and life sciences systems. They analyze the existing code, figure out what it’s supposed to do, and then speed up the process of making it modern and efficient. This is especially important in healthcare, where tiny mistakes can have big consequences. For example, systems that calculate medicine dosages or manage patient records need to produce exactly the same results after they’re updated – not just similar results, but identical ones. This is crucial for clinical trials and patient care, where accuracy is key. By using AI to help with this process, Reliqsy can make sure that these systems are updated quickly and correctly, without putting patients at risk.
When it comes to modernizing healthcare systems, Reliqsy’s framework thoroughly validates every component’s behavior before it’s deployed to production. Patient and clinical data stays synchronized between old and new systems throughout the migration process. Automated rollback kicks in when certain thresholds are met — latency exceeding 400ms or error rates surpassing 1%. Any code changes generated by AI go through Pull Request review, and engineers sign off on the modernization roadmap before code generation begins.

How to Choose Mainframe Modernization Companies for Healthcare and Life Sciences
Start with compliance certification, not technical capability
When it comes to healthcare and life sciences, you can’t just work with any vendor. They need to be able to show that they follow the rules, like HIPAA and FDA regulations. If they can’t do that, it doesn’t matter how good they are at updating technology. You have to start by checking if they meet these basic requirements. Ask to see their certifications and proof that they have experience working with regulations in your field. Also, make sure their processes create the right paperwork that regulators will want to see.
Require behavioral validation for clinical systems
When updating clinical systems, it’s crucial that they produce exactly the same results as before – not just similar results, but identical ones. To ensure this, you should ask providers how they verify that their systems are working exactly as they should be, particularly when it comes to calculating clinical data, managing patient records, and reporting regulatory information. What methods do they use for testing? How detailed is their testing? And what are they comparing their results to? Providers who have actual experience working with healthcare systems will be able to give you specific answers. Those without this experience might just give you general promises about quality that don’t address the need for precision in clinical systems.
Ask about clinical system integration experience
Healthcare computer systems don’t work alone – they are connected to other important systems like Epic, Cerner, and Meditech, as well as equipment and lab systems. If you update the main system without knowing how it works with these other systems, you can create big problems that are costly to fix and potentially harmful to patients. So, it’s crucial to ask the people doing the update about their experience with the specific systems you use and how they plan to test that everything works together smoothly during the update process.
Check zero-downtime capability for clinical operations
Hospitals are always open, so their patient record systems can’t just be shut down for maintenance. When talking to providers, it’s essential to ask how they plan to update these systems without disrupting patient care. You want to know if they have a strategy in place to run the old and new systems side by side, sync data during the transition, and have a backup plan in case something goes wrong. The way they answer this question will show whether they really understand the needs of a hospital, where systems need to be available 24/7.
Evaluate computer system validation experience for life sciences
When it comes to life sciences companies that have to follow FDA rules, they need to make sure their computer systems are validated and have the right documents. This is especially important for systems that handle regulated data. If a company updates a system without doing the proper validation, it can cause problems with the FDA and even affect whether their products get approved or not. It’s a good idea to ask about a company’s experience with FDA validation rules and what kind of documents they provide when they update a system.
