Legacy systems integration with modern applications is crucial for companies that want to leverage cloud, data, and AI without rewriting old software. At Hyverr, we use RPA to connect even mainframe systems seamlessly and without downtime.
Many organizations still run key processes on systems built years — even decades — ago. Yet, they remain reliable in banks, insurance companies, manufacturing, and logistics. These systems are stable but often closed. And that’s where the challenge lies: how to connect them with today’s world of cloud, data, and AI? Instead of costly rewrites or migrations, there’s a faster and simpler way.
In practice, RPA is the fastest and most efficient way to integrate legacy systems with modern ones — even those running on mainframes. A robot logs into the terminal or through a standard interface and performs the same actions humans would. Systems don’t need to be shut down or rewritten. At Hyverr, we specialize in such projects – quick integrations, minimal disruption, and measurable results. This makes legacy systems integration achievable in weeks, not months.
The central dispatch department needed to speed up the verification of weighing data during goods shipment. Manual checking of hundreds of records was slow, error-prone, and delayed the entire process.
With RPA, we created a solution that automatically evaluates records from the weighing system (SAP + mainframe), identifies inaccurate or missing data, and instantly notifies responsible staff by email.
Result: fewer errors, faster dispatch, and clear accountability through transparent reports – all achieved without modifying the existing systems.
In a manufacturing enterprise, we automated the processing of non-production invoices. Previously, employees manually copied data from Excel into the accounting system BPCS running on IBM i (mainframe) and then re-entered invoice numbers back into the file.
Now, a robot handles the process: it reads data from Excel, creates an invoice in BPCS via a terminal interface, returns the document number to the file, and sends the results by email.
Result: the process runs smoothly, without errors or downtime, providing instant visibility of every invoice.
In one international bank, we automated several processes based on an internal mainframe application. The robot works with the same data as human employees – it has its own login, accesses the terminal, and performs daily tasks.
These processes now run at least five times faster with zero error rate. The company gained significant time savings, operational stability, and reliability. Legacy systems integration made these improvements possible without altering the core applications.
Legacy systems integration with modern applications is not just about technology — it’s also about strategy. RPA allows you to test integration scenarios safely, without downtime or code changes. We usually start with a short pilot project where we identify a process with a clear impact and design a robotic integration via terminal or available interfaces. Within a few weeks, you’ll see measurable results and confidence that the solution scales across departments.

Integrating legacy systems doesn’t have to be complex or risky. You can connect what already works with what your company needs today — using the power of RPA. With our proven approach, legacy systems integration with modern applications is fast, secure, and seamless, even in mainframe environments.
