Update your Legacy Software with Our Holistic Modernization Approach
Modernizing legacy software can be an overwhelming task, but at SQUER, we've developed a holistic approach to ensure your success. Our experts understand the complexities involved in modernization, from decoupling business features using proven patterns like “Strangler Fig” to considering the underlying persistence and infrastructure.
By taking a comprehensive approach that also takes your organization's unique needs into account, we can significantly boost the success of your transformation. Let us help you upgrade your software legacy, with confidence we gained in many successful modernization projects.
Modernizing legacy is a journey, which is why it is important to take one step at a time
Legacy systems are too complex to be replaced in a big bang. By iteratively implementing i.e. a north star architecture, you will create alignment within your organization. This shared direction empowers your teams to make autonomous decisions in their day-to-day work while also building towards a broader vision.

- North Star Architecture
- Early Releases
To truly decouple modernized business features, the required data must follow as well
To ensure a smooth transition we gradually migrate components to the new architecture while maintaining connectivity between the old and new systems. Replicating data ensures that both systems always have the same data. This combined approach minimizes downtime and you can continue working with minimal disruption.

Evolve the organization
Modernizing legacy software means evolving the organization to support the new architecture
By empowering your teams, you can tap into their creativity and expertise to find innovative solutions. We support you in establishing code ownership guidelines that outline who is responsible for maintaining specific parts of the code. This will prevent duplication of effort and ensure that everyone is working towards a common goal.

Architecting a system is not a one-time activity. Your systems need to evolve just as your business does.
In the past, software systems were designed to be extremely durable and long-lasting. Nowadays the trend has shifted towards creating software architecture that allows for easy exchange and replacement of parts and components. By doing so, we are able to facilitate the evolution and growth of our systems. The ability to exchange components with ease makes it possible for our software to keep up with new developments and adapt to changing needs.

Build for the present but keep the future in mind when architecting and building.
When designing a software system, it is important to consider several key factors: development speed, future readiness, and scalability. Each of these dimensions is important, and optimizing for one may come at the expense of the others. We'll help you consider what you are optimizing for in the first place, and set up a solid foundation that can support future evolutions without sacrificing the speed of development or the scalability of the system.
