Legacy Modernization
Making outdated software future-ready
Is your proven software reaching its limits? We help you gradually modernize legacy systems – without jeopardizing ongoing operations and with a clear focus on your business value.
Discuss modernizationWhen legacy becomes a risk
Legacy applications that ran reliably for years can suddenly become obstacles.
Rising maintenance costs
Every change takes longer and costs more. Knowledge about the system fades with each employee turnover.
Innovation blocker
New features are nearly impossible to implement. Competition moves ahead while you struggle with legacy debt.
Security risks
Outdated frameworks and missing updates open security vulnerabilities. Compliance becomes a problem.
Talent shortage
Developers for old technologies are hard to find. New talent wants to work with modern stacks.
Strategies for your modernization
There is no one-size-fits-all solution. We find the strategy that fits your situation.
Refactoring
Gradual improvement of existing code. Clean up structures, reduce technical debt, improve testability.
Best for: Stable code that just needs modernization
Replatforming
Migration to modern infrastructure (cloud, containers) while maintaining functionality.
Best for: Working software with outdated infrastructure
Rebuild
Complete rebuild with modern stack. Often the fastest path for heavily outdated systems.
Best for: Systems where refactoring would cost more than rebuilding
Strangler Pattern
Gradual replacement with new components. The legacy system is phased out step by step.
Best for: Large, critical systems without downtime risk
Our approach
Structured and transparent – from analysis to successful modernization.
Assessment
Analysis of current state: architecture, code quality, technical debt, dependencies, and business criticality.
Strategy development
Joint development of the modernization strategy. Which areas first? Which approach fits?
Pilot phase
Implementation of a manageable area as proof of concept. Learn and adapt.
Gradual rollout
Continuous modernization in iterative cycles. Always with a working system.
What you gain
Modernization is an investment that pays off.
More agility
Implement new features faster. Respond to market demands.
Lower operating costs
Less maintenance effort, more efficient infrastructure, better automation.
Higher quality
Fewer bugs, better performance, happier users.
More attractive to developers
Modern technologies make you more interesting as an employer.
Frequently asked questions
This depends heavily on scope and chosen strategy. An assessment typically takes 1-2 weeks. The actual modernization can range from a few months to several years – but always with continuous progress.
Through incremental approach, extensive testing, and parallel operation. We never modernize the entire system at once, but in manageable increments.
Yes, that's a central goal. We plan modernization so that ongoing operations are not affected. New and old components run in parallel.
We analyze this in the assessment. Often gradual modernization is cheaper and less risky. For heavily outdated systems, rebuilding can be the better path. We recommend what makes most sense for you.
