Explore the human side of modernisation and the foundations that matter most when change is high stakes.
Get your copyAI is making legacy modernisation more critical than ever, so organisations can replace long-standing systems with modern ones that can leverage the latest agentic technologies.
However, AI itself is also making the process quicker and more achievable, so long as you have a good grasp on the fundamentals. Successful modernisation still depends on a clear strategy, sound technical decisions and a strong understanding of your business context.
At Scott Logic, we combine deep experience in complex legacy transformation with practical AI expertise to help clients modernise with confidence, so they can accelerate delivery without losing sight of what good looks like.
We’ve delivered legacy modernisation in some of the most complex enterprise environments, working with large organisations where the technology landscape is business-critical, heavily integrated and difficult to change. That experience means we understand what it takes to modernise successfully: navigating complexity, reducing risk and making progress in a way that works for the organisation as a whole.
Now, we’re applying that same hard-won modernisation experience alongside our AI expertise to help clients move more quickly. From understanding legacy estates to accelerating analysis, code transformation and delivery, we use AI in practical ways that speed up modernisation without losing sight of the technical judgement, governance and business context needed to get it right.
James Heward, Principal Architect, discusses the role of AI in modernising legacy systems, highlighting how AI tools can help decode complex, poorly documented codebases and assist in transforming them to modern platforms.

When it comes to legacy modernisation projects, there’s a kind of rework – let’s call it ‘cultural rework’ – that organisations often seem to accept as an inevitable part of their investment. In this blog post, I look at some of the main cultural, team and human challenges that arise on legacy modernisation projects, and how they can be tackled.

If you’re working on an entirely new product with no dependencies on any existing system, you’re free to decide how best to build, test and deploy the product. However, if you’re modernising a legacy system, the approach to development and testing is less straightforward. In this blog post, I look at some of the key considerations that should inform the test strategy for a modernisation project.
