Why banks should upgrade, not replace legacy systems

The biggest myth in banking technology: “We’ll replace our legacy system in two years.” Banks often tell themselves this, but the reality is usually very different. In practice, these timelines are often too optimistic. By the time the replacement is ready, the business environment has already moved on, leaving banks stuck in another cycle of catching up. Major replacement projects are also heavy on resources, highly complex and notoriously prone to overruns. When institutions try to do everything in-house, the risks multiply and innovation grinds to a halt while teams wait for the “big switch.” That is why we take a different approach with clients. Instead of ripping out the legacy system, we “upgrade” it by overlaying our software on top. This allows for smart automation and process orchestration while keeping the existing core stable. It means banks can unlock agility without the risk and disruption of starting from scratch. Do you believe in big-bang replacements, or do you see incremental transformation as the smarter path?
