5 signs your legacy IT infrastructure is harming your business

Written by Ben Keates | Feb 11, 2025 6:38:26 AM

Familiarity can be both a blessing and a curse, but when it comes to outdated technology, it doesn’t pay to be sentimental. While your legacy IT infrastructure might have been a reliable backbone in the past, it can now slow operations, inflate costs and increase security risks. Understanding the key signs of outdated systems can help you take proactive steps to modernise.

Five signs your legacy IT infrastructure is holding you back

#1: Frequent system downtime

While disruption is inevitable in business, frequent and unplanned downtime is a serious concern. System downtime disrupts workflows, causes lost productivity and erodes customer trust. A recent report from Oxford Economics estimates that unplanned downtime is costing the Global 2000 an eye-watering US$400 billion annually. If unplanned outages have become a regular issue, it’s a strong indicator that your ageing IT infrastructure is no longer fit for purpose. The costs of downtime can snowball, from missed revenue opportunities to reputational damage.

#2: Rising maintenance and support costs

Older systems often require extensive maintenance to keep running. As hardware ages and software becomes unsupported, businesses face skyrocketing costs for patches, repairs and specialised expertise. These mounting expenses can divert resources from strategic initiatives, limiting growth. In fact, according to Deloitte, over half of an IT department’s budget is spent on sustaining business operations, with a much smaller fraction left for innovation​.

#3: Inability to integrate new technologies

This is a big one. Modern businesses need to adapt to trends like cloud computing, AI and automation, or risk being left behind. There also needs to be seamless integration and interoperability among various data sources. Legacy IT infrastructure often lacks the compatibility required to integrate modern advancements, leaving organisations reliant on manual processes. This inability to evolve restricts efficiency and keeps you playing catch-up with competitors embracing innovative solutions.

#4: Poor system performance and slow load times

When employees and customers face delays due to sluggish systems, it affects productivity and satisfaction. It can be enough of a frustration that people look elsewhere for faster performance that keeps up with their needs. Legacy systems are often unable to handle increased data loads or modern application demands, leading to frustrations that harm both user experience and business outcomes.

#5: Compliance and security risks

Outdated systems can fail to meet evolving data protection standards or industry regulations and put you at risk of a host of threats and hazards. Older tech also does not receive the usual security updates and bug fixes that current systems do, as support from the manufacturer or vendor. Legacy IT infrastructure is therefore more vulnerable to cyberattacks, putting sensitive information and business continuity at risk. Non-compliance with standards could also lead to fines and reputational damage.

How to modernise your legacy systems

Acknowledging the limitations of legacy IT infrastructure is the first step. Modernising your systems doesn’t have to be overwhelming if you approach it strategically.

  • Conduct a comprehensive IT audit - Begin by evaluating your current systems to identify vulnerabilities, inefficiencies and areas that no longer meet business requirements. This audit will form the foundation of your modernisation plan.
  • Prioritise systems for replacement or upgrade - Not all legacy systems require immediate replacement. Rank them based on their impact on operations and business goals. This prioritisation ensures resources are allocated effectively.
  • Develop a transition plan - A clear roadmap is essential for a smooth transition from outdated systems. Define timelines, milestones and resource requirements. Communicate the plan to stakeholders to ensure alignment across teams.
  • Partner with IT experts - Enlisting the help of IT specialists can streamline the modernisation process. Experts bring valuable insights and experience, helping you avoid common pitfalls and implement solutions tailored to your business needs.

Out with the old

Outdated technology can no longer keep up with the increasing demands of modern business. By recognising the signs early, such as frequent downtime, rising costs, or security risks, you can take decisive action to stay competitive. Modernising your systems doesn’t just resolve current issues – it sets your organisation up for long-term success in an ever-evolving digital world.
