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
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.

step by step

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Replace outdated systems with a faster, safer, and more cost-effective incremental modernization approach that minimizes risk and keeps your business running.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