Legacy application modernisation

Move forward without losing the behavior people depend on.

An old application may contain essential business rules that exist nowhere else. Rewriting its screens before identifying those rules can turn a technical upgrade into a process change nobody agreed to.

The paid engagement

We begin with a behavior inventory and a small modernization boundary, such as a deployment repair, a supported dependency path or one replaced module. Representative records and user actions become the acceptance evidence.

Acceptance and boundaries

The proposal includes migration risks, fallback steps and what stays in the old application for now. We distinguish demonstrated behavior from assumptions. Source ownership, license rights and production access must be established before work starts.
