Legacy Application Modernization
Legacy modernisation updates old software, such as legacy PHP, older .NET, VB or desktop systems, into modern, secure, maintainable applications, usually in stages so the business keeps running. We assess the system, plan the safest path and migrate data and users carefully.
Rewriting everything at once is risky. We prefer a step-by-step approach: wrap the old system with APIs, replace parts one by one, and switch users over when each part is proven.
What we offer
- System assessmentCode, data, risks and dependencies.
- Modernisation planRehost, refactor or rebuild, part by part.
- API layerConnect old and new systems during transition.
- Data migrationClean, verified data transfer.
- Cloud readinessMove to AWS, Azure or Google Cloud.
Common use cases
- Old PHP or .NET Framework systems
- Desktop software moving to the web
- Unsupported frameworks and security risks
- Systems only one person understands

Frequently asked questions
No. We run old and new side by side and move users gradually.
It depends on code quality, business value and risk. The assessment gives a clear recommendation.
From a few months to over a year for large systems, delivered in stages.
Usually gradually. We replace parts one at a time (the strangler pattern) so the business keeps running and risk stays low.
Yes. We analyse the code and database, document how it works and then plan changes.
