Legacy modernization moves old systems to supported platforms without a risky big-bang rewrite. We assess the system, document its behaviour, then migrate incrementally using patterns such as the strangler fig, with automated tests to prove nothing breaks. We handle VB6, Classic ASP, Delphi, COBOL, PHP 5, AngularJS, Python 2 and .NET Framework.
Old to new, one slice at a time.
A simplified view of an incremental migration moving modules to a modern stack.
Built to hold up.
Assessment and documentation
Inventory, dependency maps and recovered business rules, so you know exactly what you have.
Incremental migration
Strangler-fig and parallel-run approaches that move one slice at a time with rollback at every step.
Framework and language upgrades
AngularJS to modern frameworks, Python 2 to 3, .NET Framework to modern .NET, PHP upgrades and more.
Database and platform moves
Migrate from old databases and servers to managed cloud services, with data validation.
Tests first
Characterisation tests capture current behaviour so the new system can be proven equivalent.
Questions we often get.
Incremental migration is usually safer: the business keeps running and risk is spread out. A full rewrite is sometimes right when the old system is small or beyond saving.
