Modernization Instead of Redevelopment
Many companies face the challenge that their proven systems are technologically outdated but still fulfill business-critical functions. A complete redevelopment is often risky, time-consuming and costly.
We offer an alternative: the incremental modernization of your legacy systems. In doing so, we preserve the valuable business processes and accumulated knowledge while bringing the technical foundation up to date.
Our approach minimizes risks and business interruptions while simultaneously unlocking the benefits of modern technologies. This way, you protect your existing investments and make your company future-ready.

- Continuous operation
- Incremental improvements
API-First Approach
Developing modern APIs before modernizing core functionality to enable a step-by-step migration.
- Improved interoperability
- System decoupling
- Flexibility for frontend modernization
Domain-Driven Design
Redesigning the system based on business domains to achieve better separation of responsibilities.
- Better business alignment
- Clear system boundaries
- Improved maintainability
Benefits of Modernization

Frequently Asked Questions
How long does a typical modernization project take?
The duration depends heavily on the complexity and scope of the legacy system. Smaller projects can be completed in 3–6 months, while more extensive modernizations may take 12–24 months. Through our incremental approach, however, you see initial improvements and results after just a few weeks.
Do we need to interrupt operations during modernization?
No, our modernization approach is designed to minimize business interruptions. We use techniques like the Strangler Pattern, which enables gradual migration while the system remains fully operational. Any necessary switchovers are planned in coordination with you outside core business hours.
How is our data protected during modernization?
Data security is our top priority. We implement comprehensive security measures including data encryption, secure migration processes and regular backups. All data migrations are thoroughly tested and validated before being applied to the production environment. We also strictly adhere to data protection regulations such as GDPR.
Is modernization cheaper than a redevelopment?
In most cases, yes. Modernization allows you to retain proven business logic and processes while only renewing the technological foundation. This reduces risks, development time and costs compared to a complete redevelopment. You can also protect your existing investments and invest incrementally in modern technologies.
How are our employees prepared for the modernized system?
We provide comprehensive training and documentation for your employees. Through the incremental modernization approach, your teams also have time to gradually adapt to the changes. We also ensure that knowledge transfer is an integral part of the project so that your internal teams can effectively manage the modernized system.
