Free Dependency and Risk Assessment

A full map of your codebase before any migration commitment

We analyze your .NET Framework or legacy .NET Core codebase for runtime dependencies, third-party NuGet packages that have dropped Framework support, and compatibility risks, delivering a modernization blueprint with effort and timeline ranges before you spend a dollar on migration work. Third-party dependencies are consistently the number one cause of migration timeline overruns.

Best for: any organization still deciding whether, and how, to migrate

Legacy Framework and Pattern Migration

ASP.NET MVC, Web Forms, WCF, and VB6-adjacent estates

Migration paths for ASP.NET MVC to ASP.NET Core, Web Forms to Blazor Server or WebAssembly, WCF services to modern gRPC or REST APIs, and Windows Services to .NET Background Services, each with a production-tested pattern rather than an improvised rewrite.

Best for: applications built on frameworks Microsoft has stopped actively developing

AI-Assisted Migration, Human-Verified

Automate the mechanical 60 to 80 percent, keep senior engineers on the business logic

We use current AI-assisted code transformation tooling to accelerate the mechanical parts of migration, dependency injection modernization, configuration system overhauls, Entity Framework 6 to EF Core upgrades, while senior engineers verify every change against your actual business logic. This is faster than a fully manual migration and more reliable than an unsupervised automated tool on an undocumented legacy codebase.

Best for: mid-size to large codebases where a purely manual migration would take too long, and a purely automated one is too risky

Zero-Downtime, Incremental Cutover

Strangler-fig migration, not a big-bang rewrite

We migrate incrementally, module by module, validating each piece in production before moving to the next, rather than a big-bang rewrite that leaves your business running on an unmodified legacy system for a year or more while nothing ships. Covered further, for teams also considering a service decomposition, on our Microservices Development with .NET page.

Best for: businesses that cannot tolerate a stalled, all-or-nothing migration

AI-Accelerated, Human-Verified, Not Fully Automated

Microsoft's own Copilot app modernization agent has documented limitations on large, undocumented legacy codebases. We use AI tooling to accelerate the mechanical 60 to 80 percent of migration work, while senior engineers verify every change against your actual business logic, the reliability of manual migration at a fraction of the timeline.

A Real Deadline, Handled With a Real Plan

.NET 8 and .NET 9 reach end of support on November 10, 2026. We give you a written, dependency-mapped timeline before you commit, not a generic estimate, so you know exactly whether your migration will land before that date.

Incremental Delivery, Not a Stalled Rewrite

The single biggest migration failure mode is a big-bang rewrite that stalls with nothing shipped for a year. Our strangler-fig approach delivers value module by module, with your business running throughout.

Production Patterns for Every Legacy Technology

Web Forms to Blazor, WCF to gRPC, ASP.NET MVC to Core, Windows Services to background services, each migrated with a tested pattern, not improvised on your codebase for the first time.

Free Assessment Before Any Commitment

A dependency and risk map delivered before you spend a dollar on migration work, so your business case is built on evidence specific to your codebase, not a generic industry estimate.

One Team, Migration Through Post-Launch Support

Assessment, migration, testing, deployment, and ongoing support delivered by the same coordinated team, not handed off between a tooling vendor and a separate implementation partner.

HIPAA Modernization

PHI handling upgraded alongside the framework migration

Legacy .NET Framework healthcare systems often predate current HIPAA technical safeguard expectations. Migration is the natural point to introduce modern encryption, access control, and audit logging that the original system never had.

SOC 2 Readiness Post-Migration

Security posture upgraded as part of, not after, the migration

Migrating off unsupported frameworks is frequently a direct SOC 2 audit finding remediation. We build the access control and logging architecture SOC 2 auditors expect into the migrated system from the start.

PCI-DSS for Legacy Payment Systems

Payment flows modernized alongside the framework upgrade

Legacy .NET Framework payment processing code is a common PCI-DSS audit gap, since older frameworks cannot receive current security patches. Migration is the opportunity to bring payment handling current with PCI-DSS expectations.

State Privacy Law Compliance Gaps

CCPA/CPRA, NY SHIELD, BIPA, and more, often unaddressed in legacy systems

Legacy systems built before current state privacy laws existed frequently lack consent management, data subject request handling, or deletion workflows. Migration is the point to close these gaps rather than bolt them onto an aging system.
