Legacy ASP.NET applications often carry years of accumulated dependencies, custom infrastructure and undocumented assumptions. This assessment provides a structured, evidence-based view of an existing application’s architecture, dependencies and modernization constraints before any migration work begins.

The outcome is a pragmatic roadmap: which parts of the application can move to ASP.NET Core directly, which require refactoring first, and where containerization or cloud-native patterns provide the most value - sequenced by risk and business impact rather than by technical preference alone.
