Legacy Modernisation – Rebuild. Reinvent. Future-proof.
Your systems got you this far — but they weren’t built for what comes next. We help you modernise critical enterprise scale software without disrupting the business that depends on it. Whether that means refactoring, replatforming, or a full rebuild, we bring your legacy stack into a flexible, maintainable and secure future.

Why Modernise with UWS
For more than a decade, we’ve worked with complex enterprise environments — Java-based systems, monolithic architectures, on-prem databases — and helped clients move them into scalable, cloud-native, and maintainable solutions.
Our approach combines deep engineering experience with AI-enhanced analysis tools that map dependencies, detect risks, and predict the safest migration path before a single line of code changes.
