FAQPage Schema
How do I migrate legacy ASP.NET Web Forms to ASP.NET Core incrementally?▼

Plan incremental migration from legacy ASP.NET MVC to ASP.NET Core using seam-based modernization strategies. This isolates functionality, establishes risk controls, and maintains stability while progressively moving components to the new framework.

What is seam-based modernization for classic ASP.NET applications?▼

Stabilize legacy ASP.NET applications on the .NET Framework by identifying core maintenance problems, documenting IIS-centric hosting contexts, and establishing clean seams before planning migration boundaries.

Can I modernize .NET Framework Web Forms without a full rewrite?▼

Yes, you can plan realistic modernization boundaries for legacy ASP.NET applications by applying incremental migration patterns. This allows teams to stabilize behavior and migrate to ASP.NET Core without a full rewrite.

What are the limitations of incremental migration for legacy ASP.NET apps?▼

Incremental migration for legacy ASP.NET apps is limited by IIS-centric hosting dependencies and Web Forms architecture constraints. Teams must carefully identify functional scopes and apply seam-based strategies to avoid destabilizing core behaviors.
