Legacy Systems: what are they and what is the best way to upgrade them? What are legacy systems? A legacy system is a software system that is outdated or no longer in use. These systems are often difficult to maintain and update, which can make them less effective and more prone to security risks. Many…

Welcome to an immersive exploration of the world of Legacy Systems. As we delve into this fascinating topic, we will not only unravel the intricacies of these systems but also highlight their significance in the rapidly evolving landscape of software, app, and web development.

Legacy Systems, essentially refer to outdated hardware, software or a combination of both, which were once effective in meeting specific business needs but are now overshadowed by the wave of new technologies. Despite the technological advancements, these systems often remain integral for many organisations due to their unique functionalities and customisations, data compatibility, security and the sheer cost and time, involved in initiating an upgrade or a complete system overhaul.

In a realm propelled by continuous advancement, navigating through legacy systems can appear counterintuitive. While many organisations continue to grapple with their outdated systems, others are taking the plunge and upgrading to modern, bespoke systems. These bespoke systems aren’t a one-size-fits-all solution; rather, they are meticulously fashioned to align perfectly with an organisation’s specific needs and to seamlessly integrate into the current infrastructure—providing a customised solution that’s not just effective but efficient.

The 2020 report from the Public Accounts Committee (PAC) in the UK revealed that many Central Government departments are reliant on age-old, unsupported systems leading to escalating costs and glitches. Significantly, a whopping £2.3bn was spent in 2018-19 merely on maintaining ageing technology. A similar trend is observed across sectors, though the degree varies.

Several factors contribute to this resistance to change – fear of disrupting business continuity, lack of requisite skills for new systems, budgetary constraints, or the challenge of migrating vast quantities of data to a new system. Despite these challenges, I firmly believe adopting modern technology is not just a desire but a necessity that companies need to embrace, to stay agile and competitive in the long run.
