Integrating RPA into Legacy Systems: A Safe Path to Digitalization

| ~ 5 min read

For many SMEs, old (legacy) software systems represent both a valuable database and a major obstacle to innovation. Replacing them is costly and risky. Software robots (RPA) offer an elegant solution, allowing automation without compromising the integrity of existing systems.

Why Legacy Systems Persist

Systems developed 10-15 years ago are often stable and contain the company's essential business logic. Migrating data and redesigning processes on new platforms involves time, resources, and a significant operational risk of downtime.

RPA addresses this problem at the user interface (UI) level. The robot interacts with the legacy application exactly like a human employee: enters data into fields, clicks buttons, extracts information from screens. Thus, the core logic of the system remains untouched.

Case Study: Automating the Supply Flow

We recently implemented a solution for a distributor using an old inventory management system without a modern API. The manual process involved:

  • Downloading a CSV file from the supplier's platform.
  • Manually entering over 200 order lines into the legacy system.
  • Manually checking stock levels and prices.
  • Generating and sending the order via email.

The RPA solution reduced this process from 4 hours to 25 minutes. The robot retrieves the file, parses the data, enters it into the old system, validates the information, and sends the completed order, all autonomously and with an almost zero error rate.

Best Practices for Integration

To ensure the success of such an implementation, we recommend:

  1. Identifying stable processes: Choose repetitive processes with clear rules that do not change frequently.
  2. Creating dedicated accounts: The robot should have its own user account in the legacy system for audit and security.
  3. Implementing robust exception handling: The robot must know what to do when it encounters an error or an unexpected system state.
  4. Continuous monitoring: Use dashboards to track robot performance and status.

Integrating RPA with legacy systems is not just a technical solution, but a pragmatic digitalization strategy. It allows companies to leverage previous investments while gaining efficiency, accuracy, and competitive speed in the market.
