Lower maintenance costs

Legacy software often requires specialised knowledge and resources to maintain and support, making it expensive to keep the system running. Application modernisation solutions help businesses reduce costs by unifying the tech stack within the organisation, reducing licensing costs and avoiding unexpected expenses related to system downtimes and data loss.

Top-notch security

Security vulnerabilities resulting from legacy software increase the chance of ransomware attacks, malware and data breaches – giving hackers a back door to strategic systems within your organisation.

Integrate with newer systems, technologies and microservices to improve your business functionality and dynamically customise or scale your digital product.

Improved performance

Don’t let the outdated code, poor architecture, and lack of support for modern operating systems affect your business opportunities. Modernising legacy applications will allow you to optimise the performance, improve responsiveness, increase productivity and boost revenue. Take advantage of a personalised modernisation strategy, covering performance-oriented techniques like caching, load balancing, and database tuning.

Enhanced functionality

Stay competitive, keep up with evolving customer needs and take advantage of new business perspectives. Use legacy app modernisation to improve UX/UI, integrate seamlessly with cloud platforms, deploy scalable microservices architectures or build brand new app features. Enhance the functionality of your software and ensure your product is ready for further scaling or improvements.

Better compliance

Ensure your software meets current regulatory requirements specific to your industry or region and data protection laws like GDPR or CCPA.

Getting to know your vision & business needs

First of all, we’d like to learn about your product idea and identify the scope of your project. For that, we gather all the crucial info about your business goals and expectations. We discuss the potential features, tech solutions and time required to deliver them. By the end of this stage, we should be able to provide you with a general development schedule and an estimated project price.

Diving into the details

To make sure that your custom solution becomes a success, we put together a series of personalised workshops tailored to your needs. Sample workshops can focus on Data, Product design, or Strategy – you make the final call. After we’ve answered each other’s questions and reached a common vision, we prepare the wireframes and the first design drafts, development requirements, as well as all the basic documentation of the project.

Turning your bespoke idea into reality

This is when your idea truly comes to life! We finalise the UX/UI designs and begin the development of your web or mobile application. Keep in mind, that every project is unique so there’s no one-size-fits-all way to tell how long it’s going to take, but as a rule it takes us up to 3 months to create a fully-functional minimum viable product – your MVP. That is the version of your solution ready to be released to the market.


Your app is ready to be released to the market! After the development is complete, the MVP is tested, and every stakeholder is satisfied, we take care of the deployment and release. As time is of the essence during this phase, we make sure everything goes according to schedule and the entire process is as seamless as it gets.

There’s more for us to do

Your custom digital product is released, but our work doesn’t necessarily end here. We pride ourselves in building long-term relationships with our customers; if you’d like to upgrade your product with some additional features over time, if there is a particular enhancement that you’d like to try out, or if you simply want us to take care of maintenance and support, we’re always happy to help! In case you choose to let your in-house team to take over the project, we’ll ensure the transition goes without any surprises.

Legacy application modernisation FAQ

What are legacy apps?

Legacy apps are software applications that have been developed using older technologies. These applications may have been created years ago and still run on outdated hardware or operating systems. Legacy apps are often challenging to maintain and update, as they may lack the flexibility of modern applications.

Despite their age and potential limitations, legacy systems are critical to many businesses and organisations, as they often perform essential functions and keep important data. However, as technology evolves and business needs change, legacy apps can become increasingly costly to maintain.

That is why at some point, it is crucial to modernise legacy apps. This may involve refactoring code to make it more modular and maintainable, updating the application’s user interface to improve usability, or migrating it to a newer platform or cloud environment. In some cases, rebuilding the application from scratch may be more efficient using modern development tools and practices.

What’s the process of legacy app modernisation?

The process of legacy app modernisation can be a complex undertaking, as legacy apps often may be tightly integrated with other systems. Here is a general overview of the steps involved in modernising a legacy app:

  • Evaluation and planning: The first step in modernising a legacy app is to assess its current state to identify and plan the areas for improvement. This may involve analysing the app’s architecture, codebase, and performance and identifying any security vulnerabilities or compliance issues.
  • Refactoring: This phase involves changing the app’s codebase to improve its quality, maintainability, and performance. This may include updating the app’s programming language or framework, restructuring the codebase, or removing deprecated features.
  • Updating the User Interface: The user interface of a legacy app may be outdated and difficult to use. Updating the UI can improve the user experience and make the app more appealing to users.
  • Migrating: In some cases, it may be necessary to migrate the application to a newer platform or cloud environment. This can improve performance, scalability, security and reduce maintenance costs.
  • Testing and Deployment: After the modernisation process, the app should be thoroughly tested to ensure that it functions as expected. Once testing is complete, the app can be deployed to production.

By following these key steps, software development companies can successfully modernise legacy apps, improve performance, and reduce maintenance costs while ensuring that the application remains relevant and effective for years.

How much does it cost to modernise legacy software?

The cost of modernising legacy software can vary widely depending on the application’s specific needs, the complexity of the overall modernisation process, the resources required to complete the project, or the technology chosen. Therefore, quantifying the exact cost of legacy app modernisation takes time and effort.
However, it is estimated that the cost may vary from $30 000 to $150 000 or more. Modernising an application is a good business decision because it significantly reduces product maintenance costs, increases productivity, data flow and security, and eliminates compatibility issues.

The cost of modernising legacy software can be divided into three main categories: assessment and planning, development, and deployment. The evaluation and planning phase involves evaluating the existing software and determining the scope of modernisation required. The development phase involves updating the software to meet modern standards, such as improving user experience, scalability, and security. The deployment phase involves deploying the modernised software and ensuring it works as intended.

Ultimately, the cost of modernising legacy software is an investment in the future of the software and the business. While the upfront cost can be significant, modernising legacy software can improve efficiency, increase revenue, and better customer satisfaction.
