FORES MODERNIZATION FRAMEWORK

Most applications don’t need a rewrite. They need to be made better.

You don’t need to develop a new application from scratch. Most systems can be modernized faster, more cost-effectively, and more safely.

Replace the old with the new!

Do you recognize yourself in this situation?

  • The existing legacy system works, but significantly slows down development
  • A full rewrite is too expensive
  • Fear of breaking existing functionality
  • Security and regulatory risks (NIS2, CRA)
  • Non-compliance with GDPR requirements

A solution we can provide.

  • Gradual modernization of the existing application
  • Incremental upgrade instead of a full rewrite
  • Step-by-step architectural evolution
  • Controlled decomposition and replacement of system components
  • Use of AI for analysis, migration, and testing of changes
FORES MODERNIZATION FRAMEWORK

Step-by-step modernisation of legacy applications without a complete rewrite

The old system still works. But every change takes a long time, security requirements such as NIS2 keep growing, and a complete rewrite would take up to two years and cost a lot of money. That is why we at Fores Technology Group created the Fores Modernization Framework. We modernise the application gradually, step by step, and the original and the new solution run in parallel during the transition. We test and deploy every change separately, without disrupting operations. We use artificial intelligence for system analysis, migration and testing. The result is the same as with a rewrite, it just arrives faster, more safely and at a lower cost. Delivery time is usually 1 to 4 months.

Comparison of Approaches

Modernization, not a risky full rewrite

The same result, reached faster, safer and cheaper. Here is how incremental modernization compares to a full system rewrite — across speed, risk and cost.

AI - Strategic layer

We see AI as a core part of modern software architecture, not just an add-on. That is why we integrate it from the very beginning of the modernization process.

AI in application modernization

We use AI as part of the modernization process as well as a tool for building more intelligent and efficient systems.

System analysis

We use AI to better understand existing applications and identify technical debt. It helps uncover hidden dependencies and risks in complex systems.

Architecture design

We leverage AI in architectural design to support decision-making and evaluate different solution options. It improves accuracy and consistency of system design.

Development & refactoring

We integrate AI into development workflows to automate repetitive tasks and speed up refactoring. This allows engineering teams to work more efficiently.

AI agents

We build custom AI agents that can automate parts of development, testing, or operations. These agents can be integrated directly into modernized applications.

Testing & quality assurance

We use AI to detect bugs, risks, and inconsistencies in systems. It helps us improve the stability and quality of delivered solutions.

Modernize Your Legacy Applications Without Rewriting From Scratch

Replace outdated systems with a faster, safer, and more cost-effective incremental modernization approach that minimizes risk and keeps your business running.

1. Discovery & assessment

We start by analyzing the current application from a technology, architecture, and business process perspective. We identify technical debt, risks, and the areas that cause the biggest problems or costs.

We define the modernization approach – typically incremental refactoring or a strangler fig strategy. This includes a roadmap that sets priorities, phases, and the step-by-step modernization process with a strong focus on business continuity.

We design the target architecture of the new application, including technologies, integrations, and infrastructure. We also define principles that ensure scalability, security, and long-term sustainability.

We modernize the application step by step, with the legacy and new solution running in parallel. Each change is isolated, tested, and deployed without disrupting production.

We gradually migrate data, integrations, and functionality into the new application. Each phase goes through testing, security validation, and controlled deployment.

Once migration is completed, we decommission the legacy application and fully transition to the new one. After that, we continue improving, optimizing, and extending the application on a modern platform.

FAQ

Frequently asked questions about Fores Modernization Framework

Who in Slovakia can modernise a legacy application step by step?

We do it at Fores Technology Group, a Slovak IT company headquartered in Bratislava. For step-by-step modernisation we have our own approach, the Fores Modernization Framework, with which you do not have to rewrite the application from scratch.

A complete rewrite usually takes 12 to 24 months, requires a large investment and carries a high risk for both the project and operations. New features also arrive only at the end. With step-by-step modernisation, delivery time is usually 1 to 4 months, operations continue without interruption and new features arrive continuously. Users adapt gradually and the transition is smooth for them.

In six steps. First, we analyse the application, its technologies, architecture and technical debt. Then we choose the approach, most often incremental refactoring or the Strangler Fig strategy, and prepare a plan. We design the target architecture and modernise the application step by step, with the old and the new solution running in parallel. We gradually move data and integrations and test and deploy every phase. Finally, we retire the original application and keep improving the new one.

AI helps us understand the existing application and find technical debt, hidden dependencies and risks. It supports decision-making in architecture design, speeds up refactoring and helps detect errors in testing. We also build our own AI agents, which we can integrate directly into the modernised application. We work with Azure AI Foundry, Azure AI Search and Claude, for example.

Yes, it helps. Outdated technologies bring security risks and old applications often fail to meet NIS2, CRA or GDPR requirements. We therefore design the target architecture with an emphasis on security, and every phase goes through security validation.

We refresh the user interface and UX, refactor the backend, add an API layer, integrate AI and improve performance. If needed, we move the application to the cloud.

No. The original and the new application run in parallel during the transition, and we deploy every change separately, only after testing. That protects your data and business processes from outages, and you stay in control of the whole process.
