The Importance of Addressing Legacy Technology: A Lesson from a Failed Migration

Legacy Systems: The Challenge of Letting Go

In the world of cybersecurity, one common challenge that IT administrators face is dealing with legacy systems. Despite the high costs and inefficiencies associated with IT sprawl, many organizations still struggle to phase out their old systems when adopting new technology. This not only hampers operational efficiency but also increases the workload for cybersecurity teams who have to safeguard both new and old systems.

So, why is it so difficult to let go of legacy infrastructure? Are we simply hoarding outdated technology? A recent incident in Singapore sheds some light on this issue.

The Land Transport Authority (LTA) in Singapore recently announced a transition to a new transport e-payment platform called SimplyGo. As part of this transition, two legacy stored value cards, EZ-Link and NETS FlashPay, would no longer be accepted for public transport fares starting from June. While most commuters were already using the new system or contactless bank cards, there was a public outcry over the omission of a key feature from the new system.

The existing EZ-Link ecosystem allowed commuters to view fare deductions and card balances as they passed through train station gates and bus card readers. This feature was highly valued by commuters, especially the elderly who may not be tech-savvy. The backlash against the new system prompted the LTA to backtrack on the migration and maintain the existing infrastructure until at least 2030.

Transport Minister Chee Hong Tat acknowledged the “judgment error” in pushing through the SimplyGo system without considering the importance of the missing feature. He also highlighted the technical challenge of retrieving fare and card balance data in real-time for account-based ticketing cards like SimplyGo.

This incident highlights the importance of user buy-in and understanding user needs when implementing new technology. Underestimating the importance of key features can lead to resistance to change and the retention of legacy systems. This not only incurs higher operational costs but also creates additional security risks.

The Singapore government now has to allocate an additional SG$40 million to maintain the existing system, which could have been avoided with better planning and user testing during the development process of SimplyGo. It serves as a costly lesson for the country and emphasizes the need for organizations to prioritize user benefits when adopting new technology.

In today’s rapidly evolving technological landscape, organizations must keep their focus on the users and their needs. Overlooking key features can derail an entire migration plan and prolong the lifespan of outdated systems. By understanding user requirements and involving them in the
