Modernising Legacy Systems for AI Readiness
In his Tech in Motion keynote, Radu Vingan, Tribe Lead at Accesa, explored how AI dreams often crash into legacy realities and what to do about it. Discover valuable insights about smarter decisions, predictive systems, and automation.
Every organisation today wants to embrace AI. The idea is simple: smarter decisions, predictive systems, and automation that just works. Yet many of these ambitions collide due to legacy processes.
In theory, AI is all about intelligent models. In practice, it’s mostly plumbing, connecting systems, managing data flows, and ensuring everything speaks the same language. And like with real plumbing, ignoring the leaks doesn’t make the problem go away. It just means you’ll spend more later trying to fix what’s already broken.
When you look under the hood of a typical “AI-ready” project, what you often find is not readiness at all, it’s fragmentation. Data comes in twenty different formats from twenty different systems. Key applications have no integration between them. Multiple versions of the truth circulate between teams, and critical documentation exists only in someone’s memory. In that environment, AI cannot deliver value.
The real enablers of AI are modernisation, integration, and data readiness
Modernisation means updating legacy systems into modular, scalable architectures that can adapt instead of resisting change. It’s about shifting from tightly, outdated applications to ones that can evolve where new capabilities like AI can be added.
Integration is what turns data into something usable. When information is locked away in separate systems, it might as well not exist. Real integration requires data pipelines, APIs, and event-driven flows that connect systems, devices, and teams in real time.
For AI to work, data must be structured, consistent, governed, and owned. It must be trusted and accessible, not hidden in private folders or duplicated across systems. Without that, AI remains more of a concept slide than a working solution.
From Ambition to Foundation
It’s tempting to start an AI project by building a model. But more often than not, the model is the easy part. The hard part is what comes before it: connecting disparate systems, cleaning inconsistent data, and modernising the software landscape so the model has something reliable to learn from.
A sustainable AI initiative starts by consolidating data sources into a common layer, one that can handle both cloud and on-premises environments, depending on regulatory or operational needs. This layer manages access and identity across applications, ensuring that data can be securely shared between devices, teams, and systems.
On top of that, a data management platform can unify structured and unstructured data, offering a single point of truth. It doesn’t necessarily replace every legacy component; in some cases, it wraps around them, creating an organised and self-contained environment where information flows predictably.
Once the modernisation and integration layers are in place, an AI platform or “AI factory” can be built. This factory becomes the central space for managing AI initiatives, training models, deploying them safely into production, and governing their lifecycle. It’s where experimentation turns into scalable intelligence.
When the foundation is right, everything else accelerates.
AI Starts with Us
Modernisation is not only a technical process, but also a mindset. It starts with those who build and maintain systems every day.
Developers and engineers can make a difference by refactoring legacy code, modularising old applications, and designing systems that can evolve. Every decision to simplify an interface or document a workflow reduces friction for future AI efforts.
Architects, analysts, and project managers play a crucial role as connectors. They translate business requirements into technical design, identify where data breaks, and ensure that processes align before timelines do.
The leaders, the sponsors of these initiatives, shape the outcome through their priorities. When they invest in the underlying foundation rather than just visible features, they create the space for AI to grow responsibly and sustainably. Lastly, sponsors should engage the technical team as early as possible to help define the foundation and ensure its approach is developed from the right perspective and in an effective manner.
