Legacy technology is quickly becoming the silent killer of business growth. With 22% of IT leaders still relying on outdated systems and 85% planning urgent upgrades, companies using legacy tech face mounting security risks, inefficiency and spiralling costs. James Green, VP of Service Operations at OneAdvanced, explores how forward-thinking IT leaders are navigating the tough transition to modern solutions.
IT systems are no longer just operational tools; they are strategic assets that enable growth, efficiency and innovation. Yet, as many businesses continue to rely on outdated systems, the risks – ranging from security vulnerabilities to stunted productivity – are mounting. For IT leaders, the challenge is clear: they must navigate the transition to modern solutions while overcoming organisational barriers, including budgetary constraints and stakeholder buy-in.
However, a significant proportion of organisations face risks tied to outdated IT infrastructures. Legacy systems often lack the robust cybersecurity measures needed to face modern threats head-on. Therefore, it’s no surprise that cybersecurity becomes a top priority for 52% of IT leaders in 2025, underscoring the urgent need to modernise.
However, legacy systems frequently cannot integrate with emerging technologies like AI or IoT, creating operational silos and inefficiencies. In fact, 34% of IT leaders cite integration issues as a key barrier to innovation. Additionally, outdated systems exacerbate compliance risks. With regulations becoming increasingly stringent, organisations reliant on older technologies may struggle to meet new standards. As compliance remains a significant challenge, a lack of updated infrastructure can make it harder to adapt to evolving regulatory requirements, leaving businesses exposed to fines and reputational damage.
The challenges of Digital Transformation
Despite understanding the risks, IT leaders encounter significant obstacles when advocating for technological transformation. Budget constraints are the most cited challenge, with 44% of IT leaders indicating that financial limitations hinder innovation efforts. This sentiment is echoed by 51% of business leaders, highlighting a disconnect between the perceived value of IT investments and their actual business impact.
Another pressing issue is the lack of buy-in from senior leadership. While IT leaders recognise the strategic importance of technology, only 20% feel their organisations view IT as a critical driver of business success. This gap creates hurdles when seeking funding or approval for modernisation initiatives. Indeed, 27% of IT leaders face difficulties convincing stakeholders of the benefits of new technologies, reflecting a broader need for better alignment between IT departments and the C-suite.
Moreover, talent shortages will only increase as we move into the new year. With businesses increasingly adopting advanced technologies like AI, the demand for skilled professionals grows. Yet, only 30% of IT leaders believe the UK has sufficient expertise to safely and effectively implement AI solutions. Without the right talent, even the most promising technologies may fail to deliver their intended benefits.
A way forward
To overcome these barriers, IT leaders must build a compelling case for modernisation that resonates with the C-suite. The key lies in demonstrating how technology investments align with broader business objectives. For example, modern systems can drive revenue growth by enabling faster, more accurate decision-making through advanced analytics. With 50% of IT leaders prioritising data management and analytics, this is an area where investment can deliver immediate value.
Technology upgrades can also streamline operations and eliminate inefficiencies. Automation tools and workflow optimisation are high-priority areas for many IT leaders, as they free up resources for strategic initiatives, increasing overall productivity. Moreover, the critical role of IT in protecting against cybersecurity threats and ensuring regulatory compliance cannot be overstated. Demonstrating how modern systems safeguard the organisation’s reputation and bottom-line can strengthen the case for investment. The flexibility and scalability offered by modern IT solutions, particularly those involving cloud-based infrastructure, also make a strong case. The shift to scalable models allows businesses to align IT costs with actual usage, addressing concerns about upfront expenditures.
Transitioning from legacy systems to modern IT infrastructures is no small task, but with a strategic approach, it can be accomplished effectively. A thorough audit of existing IT assets is an essential first step, as it helps identify gaps and prioritise areas for improvement. This assessment can pinpoint which systems are stalling productivity or exposing the organisation to security risks. Engaging C-suite executives, department heads and other key stakeholders early in the planning process is also crucial. Their insights can help align IT initiatives with business objectives, making it easier to secure buy-in. Rather than attempting an all-at-once overhaul, it’s more practical to implement a phased approach to modernisation. Focusing on high-impact areas first, such as cybersecurity or data management, can demonstrate early wins and build momentum for further changes.
Finally, partnering with IT outsourcing providers can also be pivotal in addressing skill gaps and streamlining the transition. Indeed, 76% of organisations now rely on IT outsourcing providers for some or all of their IT needs. Outsourcing can offer access to specialised expertise, reduce costs and minimise operational disruptions. Additionally, organisations should invest in training initiatives to equip employees with the skills needed to adapt to new technologies. Training not only improves adoption rates but also addresses resistance to change – a challenge cited by many IT leaders.
The cost of inaction is too high for businesses to ignore. Organisations that fail to upgrade their IT systems risk falling behind competitors, losing top talent and exposing themselves to cybersecurity threats. Conversely, those who embrace modernisation can unlock new efficiencies, drive innovation and position themselves for long-term success.
But let’s not forget that IT leaders have a critical role to play in this journey. By articulating the strategic value of technology and addressing barriers head-on, they can lead their organisations toward a future defined by resilience and growth. The path may be challenging, but with the right strategy and support, the rewards far outweigh the risks.
