I will upgrade your legacy asp net or classic asp app to modern dot net

Your application still works, but it is stuck on a version of .NET nobody wants to touch any more.

Senior .NET engineer with 200+ projects delivered over 13+ years across Fiverr, Upwork, Freelancer and direct clients. On Fiverr: 5.0 rating and zero cancellations. I have rewritten a Classic ASP system into .NET 10 for a US public-safety client and migrated production workloads off Windows and IIS onto Linux, cutting hosting cost by 54%.

WHAT I MIGRATE

Classic ASP and VB legacy systems. .NET Framework 4.x to .NET 8 or 9. Old ASP.NET Web Forms and MVC. Web Services and WCF to modern REST APIs. On-premise servers to Azure, Docker or Linux. SQL Server upgrades and schema cleanup.

HOW I DO IT

I read your existing code first and tell you honestly whether a staged upgrade or a rewrite makes more sense. Business logic is preserved and verified against the old system, not guessed at. Where the old app must keep running, I migrate in phases so nothing goes dark.

WHAT YOU GET

A modern, supported codebase that builds and deploys cleanly, full source code, and a written note of what changed and why.

Send your stack details and I will scope it honestly.
