Partial or full replacement of legacy systems

When modernisation is no longer enough, we replace your legacy application – step by step or entirely, with new development or suitable off-the-shelf software. Without a risky big bang and without losing data.

When does it make sense?

  • The technology can no longer be modernised sensibly.
  • Business requirements have changed fundamentally.
  • Operating, licence or hardware costs have become too high.
  • Standard software now covers your needs well.

What we do

  • Partial replacement: we carve out functions step by step (strangler fig pattern); old and new systems work together
  • Full replacement: AI-assisted new development on a modern, open technology stack
  • Vendor-neutral support with make-or-buy decisions, selection and rollout of standard software
  • New data model and safe data migration with cleansing, validation and trial migrations – backed by long experience in databases and data architecture
  • Parallel operation, acceptance testing and orderly decommissioning of the old system
  • Support with requirements specifications for tenders

What you get

  • A modern, maintainable application – and the source code belongs to you
  • Fully migrated and verified data
  • Documentation and training for users and IT
  • Archiving concept for legacy data, e.g. for retention periods
  • Orderly shutdown of the old system

Lower risk: with incremental replacement, a working overall system is in operation at all times. Every stage delivers immediate value – and you set the pace.
