Legacy Migration in Healthcare: Understanding the Need

Keep reading this content piece to make an educated decision. Here, you will explore the challenges of relying on legacy hardware for healthcare IT leaders. You will also get a comprehensive knowledge of the strategic paths forward for a more resilient and efficient future.

The Types of Legacy Systems in Healthcare

Not all healthcare legacy systems are the same. Common examples include:

• Electronic Health Record (EHR) Systems: Legacy EHRs are designed to maintain patient records. Many of them were supported by proprietary hardware platforms, such as VAX or AlphaServer. Unlike modern EHRs, their operating environment is not stable.
• Billing and Claims Processing: These financial systems are crucial to the functioning of a healthcare provider. A lot of them run on aging mainframe or midrange machines that are difficult (and expensive) to maintain.
• Medical Imaging and Diagnostics: Devices such as MRI and CT scanners sometimes depend on particular computer hardware (such as Sun SPARC workstations) for image processing and storage. If this hardware becomes defective, the whole diagnostic device may no longer be operational.
• Laboratory Information Systems (LIS): The LISs that manage test orders and results often run on legacy, dedicated servers. The software is reliable, but its hardware is a growing single point of failure.

Keeping Aging Hardware vs Legacy Migration

Every piece of hardware has a lifespan. Healthcare IT teams face a choice: try to keep the old equipment running at all costs or replace it. Let’s break down each of these choices:

Takeaway: whichever path you choose for the time being, replacing the aging hardware in the future is inevitable. Because critical healthcare application works around the clock, making downtime a non-negotiable thing.

Top Methods for Migrating Healthcare Legacy Systems

When the hardware can no longer be sustained, you must find a new home for your critical applications. Here are the primary strategies, with a clear focus on decoupling the software from the risky hardware.

Rehost

Rehosting, or lift and shift (hardware emulation), moves your existing application to a new environment without making changes to your legacy code or data. Instead of running on physical rack servers, your application can run on virtual machines in a modern cloud or on-premise environment.

If your on-premises cost is rising, prompting you to close the heavy data center while keeping your existing legacy applications – this strategy offers a fast, cost-effective, and disruption-free path ahead.

In other words, it’s often the quickest way to eliminate dependency on outdated hardware without modifying the critical application.

Replace

Sometimes, a modern SaaS solution exists that can replace your legacy application’s functionality. You might find a vendor that meets your core needs, with options for custom features or plugins.

While this approach offers access to advanced functions, it requires a complete operational shift and significant investment. It also means leaving your trusted, time-tested application behind.

Rebuild

If your application is inseparable from its original, ancient hardware environment, you can attempt to rebuild it from scratch. This involves documenting every function and commissioning developers to create a new version using modern code.

This approach gives you a custom-fit solution but demands massive development time and resources, creating major disruption.

Refactor & Rearchitect

Perhaps you’ll even have to modify the source code of the application a little (or add small adjustments) so that it works optimally on the new hardware. This is what refactoring provides.

As compared to rehosting, this approach involves significant changes to the application’s structure, optimizing for cloud-native capabilities. So it’s going to take more development effort and testing than the simple rehost.

Steps to Migrate Healthcare IT Systems

Migrating also requires preparation to succeed. Below are the key steps that will help you prepare for a successful healthcare legacy system migration.

• Perform a Full System Check: First things first – assess your system. Evaluate which systems are most likely to fail. Then check their performance, security risks, and maintenance.
• Prioritize Your Initiatives: You can’t replace everything at once. Prioritize migrations by risk and business impact. What would be the worst system failure for patient care or operations? Start with that first.
• Establish a Clear Roadmap: 74% of companies fail to complete their legacy migration project, leaving their critical applications still running on outdated hardware and draining budgets. But what about the 26% who get it right? They have a clear roadmap, outlining goals, checkpoints, and deadlines.
• Adopt Agile Methodologies: Turn the migration project into small phases. That way, your team can concentrate on the process of doing one thing at a time – testing thoroughly before moving to the next. This incremental model reduces risk and interruptions.
• Invest in Change Management: Because the end-users may not see a change in the application, but your IT team will be operating a new virtualized environment. Train them so that they are comfortable with the new platform.
• Form Technology Partnerships: Specialized knowledge can make all the difference when it comes to legacy migration. Get in touch with experts in hardware emulation and legacy system migration. With their expertise, you will get real insights and end-to-end support to make a smooth transition.

How Stromasys Can Help You: The Best of Both Worlds

What if you could continue to run your mission-critical healthcare applications in the same way that you do today, but on modern, reliable infrastructure?

That is precisely what Stromasys Charon solutions deliver. We offer a third option beyond the choice of maintaining or migrating.

With our Charon emulator, you can effectively recreate a virtual version of legacy hardware. The new virtual hardware imitates legacy hardware. The mission-critical application and its native operating system will keep running as if they are running on the original hardware. The result is a modern, cost-effective hardware infrastructure and true, mission-critical enterprise-level performance.

Your proven, stable legacy application is simply lifted and shifted into this new virtual environment. No code changes. No lengthy redevelopment projects. No risky data migrations.

You escape the costs and risks of aging hardware while preserving the software investment you’ve relied on for decades.
