Legacy modernisation consultant
Outdated systems are one of the biggest IT challenges in established organisations. We find specialists who can help assess, plan and execute the modernisation of legacy systems — without compromising business continuity.
What does legacy modernisation involve?
Legacy modernisation is about transforming outdated systems into modern, maintainable and scalable solutions — without disrupting day-to-day operations. It requires a structured approach and experienced specialists.
- Assessment and mapping: Evaluation of the legacy system's condition, dependencies and modernisation potential.
- Re-platform vs. re-write: Strategic choice between moving to a new platform or building from scratch.
- Strangler fig pattern: Gradual replacement of legacy functionality with new services.
- API-first approach: Setting up an API layer in front of the legacy system as a first step towards modernisation.
- Risk management: Parallel operation, fallback strategies and testing to minimise business risk.
Which consultants do you need for legacy modernisation?
Legacy modernisation requires consultants who can navigate complex existing systems while simultaneously designing the architecture of the future.
- IT architects: Design of the modernisation strategy and the future target architecture.
- Software engineers: Implementation of new services, API layers and migration of business logic.
- API specialists: Design and implementation of API layers for integration and modernisation.
- IT project managers: Management of the modernisation project with focus on risk and business continuity.

?Frequently asked questions
QWhen does it make sense to modernise rather than build new?
It depends on the system's condition, business criticality and the cost of replacing it. We can find consultants who help with assessment and the strategic decision.
QWhat is the strangler fig pattern and when do you use it?
Strangler fig is a modernisation strategy where new functionality gradually replaces the old system piece by piece — rather than one big bang migration. It significantly reduces risk.
QCan you find consultants who know our specific legacy technology?
We activate our network of 100+ vendors and screen specifically for experience with the technology you use — whether that is COBOL, Delphi, older Java EE or other legacy technologies.
