Strategic Migration

Legacy Modernization

Without Business Interruption

Your system is running, but every change feels like surgery on a living patient? I modernize legacy systems step by step - without big bang, without business standstill.

Signs Your System Needs Modernization

These symptoms indicate that action is required

Code Areas Nobody Touches

"Don't touch that, nobody understands it anymore." Classic symptom of technical debt that has gotten out of control.

PHP 7.x or Older

PHP 7.4 reached EOL in November 2022. Security updates are no longer coming. Migration is mandatory.

Outdated Frameworks

Symfony 3, Laravel 5, Shopware 5 - all without active support. Each new feature becomes a security risk.

Deployment as "Event"

When deployments require a meeting, something is wrong. Modern systems deploy 10x daily without drama.

My Approach: Strangler Fig Pattern

Step-by-step replacement instead of risky big bang

Analysis & Mapping

Understand the existing system. Identify dependencies, find pain points, create migration roadmap.

Build Parallel

New components are built alongside the old system. Feature by feature, module by module.

Gradual Cutover

Traffic is gradually redirected to new components. Old parts are shut down when no longer needed.

Decommission

After successful migration, old system is cleanly shut down. Documentation updated, team trained.
