A legacy application or legacy system can be defined in a number of different ways. It might fail to meet the needs of a growing business. It might no longer be supported, either by your IT provider or by the publishers of the software. The maintenance, support and improvements for it may have become increasingly financially prohibitive.

If you're reading this it may be because you're concerned that your current application or system has become outdated and is impairing and putting your business at risk.


We will work with you to:

  • Fully understand your current challenges

  • Quickly provide security and peace of mind for your existing critical business functions

  • Develop a roadmap to modernise your system and business software systems

  • Reveal new ways to improve satisfation for your employees and your customers

  • Provide your business with faster performance, higher quality and scalability for whenever required

Approaches to Legacy Application Modernisation

The approach to take to modernise your legacy system depends on your business. The ways to modernise a system broadly fall in to these approaches:


The entire system is rebuilt from scratch using modern development technologies and practices.

This approach is useful for organisations who prefer to work with something that is completely new or where one of the other approaches would not be suitable.



Instead of modernising the existing system itself, an additional application is developed to provide the functionality that is missing.

This approach is used when it is not viable for the legac
y system to be replaced but where you can not commit to a full redevelopment.


This approach involves replacing the system in stages whereby each component is transitioned to new technology.

Typically this would involve breaking the application into smaller, more modular components. The components would form part of a microservices architecture. The backend processes would become modernised first and would conclude with the frontend being modernised.


If it is not viable for you to commit to moving to modern technology, it can sometimes be possible to make improvements to the existing system.

In this situation typically the technology can have minor upgrades, code can be refactored (improved) and design patterns can be investigated.

Application Modernisation Benefits

Improved efficiency and productivity

Outdated applications can be slow, unreliable, and inefficient, causing delays in the business process. Modernising the application can improve the system's speed and performance, enabling employees to work faster and more efficiently.

Reduced costs

Legacy applications require expensive hardware, software, and maintenance. By modernising the application, organisations can reduce infrastructure costs and streamline maintenance costs, making it more cost-effective in the long run.

Better user experience

Modernised applications are designed to meet the latest user interface standards, making them more user-friendly and easier to navigate. With an improved user experience, customers are more likely to engage with the application, increasing customer satisfaction.

Increased security

Legacy applications are more susceptible to security breaches due to outdated security measures. Modernising the application can improve security by implementing advanced security protocols, safeguarding sensitive data, and protecting against cyber attacks.

Better integration

Modern applications can be integrated with newer software and technologies, enabling seamless integration with other business applications. This integration improves collaboration and communication across different departments and teams, leading to better decision-making.


Modernised applications are designed to be scalable, enabling them to grow as the business expands. It means that organisations can quickly adapt to new market conditions and changing business requirements.

Competitive edge

Modernised applications can give organisations a competitive edge in the market. With updated software, businesses can quickly respond to customer needs, outpace competitors, and deliver services more efficiently.

In conclusion, application modernisation is a critical process that can bring numerous benefits to businesses. By improving efficiency, reducing costs, improving user experience, increasing security, enabling better integration, offering scalability, and providing a competitive edge, businesses can stay competitive and agile in an ever-changing market. It is, therefore, essential to adopt a proactive approach to application modernisation and stay updated with the latest software and technologies to meet business objectives.


Application Modernisation

Examples of Legacy Applications and Systems

Typical applications and systems that would be suitable for modernisation include:

Windows-based desktop and server applications

Legacy windows desktop and server applications are installed on both the employee desktop and on a local server at your office. These applications are either upgraded manually or automatically each time an update is required. The desktop applications will typically connect to your local server or directly to a local database server.

In this situation you are likely experiencing problems with:

  • Increasingly poor performance

  • Inconvenience with updates and upgrades

  • An aging and limited user experience with poor user interface (UI) and user experience (UX)

  • Concerns about data backup, redundancy and security

  • Limited or no ability to enhance and improve the application

  • Lack of functionality to use the application outside of the office environment

Application modernisation will provide the following benefits:

  • Significant performance improvement

  • Updates and upgrades with no downtime for employees or customers

  • A modern, fast and easy to user interface (UI) and user experience (UX)

  • Complete peace of mind with data backup and security entirely managed

  • Ability to use the application externally such as remote working for employees

Legacy Websites

You may have had a website running for many years which has never been upgraded. Typically, it would be hosted by the development company who produced the website or by a third party hosting company that you don't have an active relationship with. You may have some ability to customise the website, but it's likely that either changes are not possible or that changes need to be submitted to the developers who created the site to make the changes on your behalf.

Some typical problems with this situation include:

  • Does not work correctly for mobile and tablet visitors - which now make up a majority of users

  • Limited or no ability to easily maintain content on the website

  • Falling rankings in search engines and no way to improve the SEO on your site

  • Website is hosted with a development company or third-party hosting company

  • Never seen performance or accessibly metrics

  • Inability to add new functionality or modify existing functionality
