.NET Migration Services

.NET Migration with Minimal Business Disruption

SanguineIT migrates ASP.NET Framework applications to modern .NET 8 and Azure — for enterprises running legacy web apps, WebForms, WCF services, and on-premise IIS deployments that need security updates, cloud scalability, and long-term Microsoft support.

Our migration programs include codebase assessment, dependency analysis, incremental strangler migrations, API extraction, database compatibility testing, and staged cutover with rollback plans — aligned to change-control processes enterprise IT requires.

See our ASP.NET development and legacy systems migration practices for broader modernization scope.

.NET migration capabilities we deliver

• Framework to .NET 8 — ASP.NET MVC, Web API, and WebForms modernization paths.
• Azure cloud migration — App Service, containers, and managed SQL transition.
• WCF to REST/API — Service modernization with backward-compatible endpoints.
• Database migration — SQL Server compatibility, EF Core upgrades, and query tuning.
• Incremental delivery — Strangler fig patterns to reduce big-bang release risk.
• Testing & validation — Regression suites and UAT support before production cutover.

Migrations planned for continuity — not just code conversion

.NET migration fails when teams treat it as a syntax exercise. SanguineIT maps business-critical workflows, identifies third-party dependencies early, and sequences work so production systems stay available while modern components come online behind feature flags and routing rules.
