    Legacy Modernisation

    Replace ageing systems without stopping the business

    Big-bang replacements fail. We modernise in slices: put an API layer in front, move functionality piece by piece, migrate the data carefully and retire the old system only when nothing depends on it anymore.

    Legacy Modernisation

    Why Liplyn Information Group for your sector

    Strangler approach

    Incremental replacement with a working system at every step.

    Data migration

    Cleansing, mapping and reconciliation with full audit trails.

    API layer

    Decouple consumers from the legacy core so change becomes possible.

    Risk control

    Parallel running, reconciliation and rollback at every cutover.

    Faster releases

    Automated tests and CI/CD replace month-long release cycles.

    Knowledge recovery

    Reverse-engineer undocumented business rules before they're lost.

    A migration path you can defend

    First we understand what the old system actually does, then we plan the smallest safe steps to replace it.
