USE CASE: APPLICATION MODERNIZATION

.NET Framework to modern .NET migration

Sanciti AI migrates .NET Framework applications to modern .NET and cloud-native architecture, from code analysis through testing. A regional insurer moved policy, claims and billing off .NET Framework on Windows Server at 50% lower cost, with more than 90% of testing automated.

Why .NET Framework applications are hard to move

Many .NET Framework applications were built as one large solution tied to on-premises Windows Server. Modules depend on each other in ways that are not written down, so a small change needs a full regression cycle.

Moving to modern .NET is more than a version upgrade. The application usually has to be split into services before it can run well in the cloud.

How Sanciti AI migrates .NET Framework applications

This is how the work was split for the regional insurer.
1

Sanciti RGEN

Mapped the dependencies between policy, claims and billing and found the coupling points that blocked separate deployment.
2

Sanciti CodeGen

Generated a separate .NET 6+ service for each domain, with REST APIs and cloud-ready deployment artifacts.
3

Sanciti TestAI

Built functional, regression and cross-module tests, focused on the interactions manual testing had missed.
4

Sanciti LEGMOD

Governed each wave and kept regulatory traceability inside the pipeline.

FAQS

Yes. Sanciti AI migrates .NET Framework applications to modern .NET, such as .NET 8, and to cloud-native architecture.

No. RGEN maps the dependencies first, and LEGMOD moves one domain at a time based on risk.

TestAI generates regression and cross-module tests from the existing behavior and runs them before each wave goes live.

The generated services are cloud-ready for AWS or Azure. Sanciti AI itself runs in a single-tenant private VPC in your account.
