Legacy Migration

Your existing system is holding you back, but a full outage isn't an option. Migrations rarely fail because of the new technology. They fail at the transition: missing rollback strategies, underestimated data complexity, unplanned downtime.

We migrate complex applications to modern technologies, with a clear rollback plan and full data continuity. Typical scenarios: PHP monolith to Next.js, proprietary CMS to Contentful, on-premise to cloud, monolith to decoupled services.

How we work

Our approach is phased. We analyze the legacy system, rebuild in parallel and migrate step by step, with checkpoint reviews and a documented contingency plan. A big-bang go-live without a safety net is not something we do.

What you get

  • Migration to modern technologies with zero downtime
  • A clear rollback plan and documented contingency plan
  • Full data continuity
  • Checkpoint reviews in every phase
  • A gradual, controlled transition instead of a risky big bang

Reference

We guided Gerolsteiner and Zellerfeld through technically complex system migrations.
