Application modernisation
Unlock value faster and reduce risk with application modernisation solutions that improve system performance, reduce costs and enable your organisation to embrace new technologies.
Bring your applications up to date with our proven framework
Advances in technology, rapidly changing business and customer needs and evolving security threats may mean that the applications you invested in are no longer delivering value. Teams struggle to work efficiently, which pushes up operational costs, while a lack of agility makes it more difficult to respond to new opportunities. Worse still, these applications could pose a security risk to your business.
We take an AI-first approach to application modernisation and use technologies like cloud computing, microservices, containerisation and embedded real-time analytics.
Our talented teams deliver high-quality results and value for money using a proven methodology to update your legacy systems with modern applications that reduce costs and improve operational agility, system scalability and security.
Solve your legacy application challenges
Legacy applications may contain system software and libraries that are out of support or no longer receive patches for security vulnerabilities. This puts your business at risk of downtime or a security or compliance breach.
Reliance on old technologies can be a barrier to business performance and agility because you miss out on the capabilities new ones offer, such as automation and autoscaling.
Legacy applications tend to be slow and unreliable, as well as difficult and costly to maintain.
Legacy on-premises hardware is costly to maintain, upgrade and replace.
Choose the right application modernisation strategy
We offer three modernisation strategies. The one you choose depends on your budget and priorities.
Migrate to the cloud and re-platform using optimisations from your chosen cloud service. This approach saves hosting costs and removes infrastructure security vulnerabilities.
Modify the application code base to work better with your chosen cloud environment. This approach will address software security vulnerabilities.
Maximise the benefits of all the latest technologies including artificial intelligence (AI). This approach addresses software vulnerabilities and maximises business agility.
Business outcomes
Lay the groundwork for growth
Modernisation helps you unlock the value of both new and existing technologies. Our proven methodology is designed to do this quickly, while minimising risk. Our team will work with you to understand your requirements, recommend and deploy the most effective solutions and technologies, then help you develop a roadmap that supports continuous improvement.
Improve workflows
Modernised applications execute faster using fewer resources, so your teams can work more efficiently and productively, with a better user-experience.
Adopt new technologies
Become future-ready with modern applications that allow you to implement technologies like AI, which gives you the agility, efficiency and automatic scalability you need to grow.
Embrace automation
Automate business processes to improve operational efficiency, compliance and resource allocation.
Unlock value faster and reduce risk
We take a phased approach to modernisation projects, keeping risk below an agreed level while delivering benefits early on and build up incrementally.

Case study: Taking legacy architecture to the cloud at Lowell
NashTech was the key partner for us in building a modern target architecture. Within a short time, we established a platform in the cloud that is connected to our legacy world, both technically and process-wise. Containerisation, continuous deployment, microservices approach, DevOps and agile teams are just a few results of the fabulous collaboration.
Lowell is Europe’s leading credit management company and chose NashTech to modernise its legacy application estate and create a single, cohesive ecosystem. Based on a Microsoft .NET core and microservices architecture on Azure cloud the new system delivered significant improvements in performance and a responsive consumer-facing website.
Case study: Driving digital transformation during turbulent times
We can’t deliver without NashTech. With the ability to scale quickly and at a reasonable cost, I’m really impressed with the quality that NashTech has provided.
When the pandemic struck, Trinity College London had to adapt quickly to the changing educational landscape. It partnered with NashTech on transformative digital initiatives enabling candidates to take digital exams. NashTech helped modernise the College’s legacy application estate to support new applications and systems that have ensured it continues to ride the wave of digital transformation in the education sector by enhancing the user experience and strengthening its relationships with candidates and customers.
Case study: The Open University unlocks benefits of new technologies
NashTech’s involvement has been critical to delivering robust development deploys for the last two years, its offshore team going the extra mile when needed. They are the hidden, but vital, element to a smooth-running platform that showcases the very best of Open University teaching to the world.
The Open University is a leader in online higher education and partnered with NashTech to reduce legacy infrastructure costs and migrate to the cloud. A true collaboration between the teams, NashTech implemented new technologies including Moodle, AWS and a scalable microservices architecture, as well as delivering a mobile-optimised website enhancing the learning experience and security.
Frequently asked questions
There are many clear signs your applications need modernising. Typically, these include performance issues, rising maintenance costs, difficulty meeting modern compliance standards limited integration, outdated interfaces and growing dependency on unsupported software, hardware or niche skill sets.
Common challenges include the risk of downtime, a lack of documentation regarding legacy systems, embedded business logic, preserving data integrity and security during migration and rising costs due to scope creep or underestimating technical debt.
The right approach depends on your application’s current state, business goals and future scalability needs. Re-factoring is ideal if your application functions well but needs to be updated to fit modern architectures like microservices or cloud-native platforms. Replace works well when the legacy application is outdated, unsupported or no longer meets your needs. Replatform offers the middle ground that lifts your application onto a modern infrastructure (such as the cloud) with minimal code changes. This improves performance and scalability without the cost of full redevelopment.
Modernising your applications can improve performance, user-experience and security while reducing maintenance costs. It also enables integration with new technologies, faster feature delivery and better scalability. Ultimately, it supports business agility and long-term growth.
