.NET Migration Services
When end-of-life .NET Framework apps slow innovation and create security risks, Atharva ITS modernizes .NET applications through framework upgrades, code refactoring, and data migration to deliver improved performance, cloud readiness, and long-term maintainability without disruption.
Why Choose Our .NET Migration Services?
Reduced technical debt: We refactor deprecated APIs, remove unused dependencies, modernize authentication patterns (OAuth/JWT), and restructure monolithic code into maintainable modules, making feature development faster and safer.
Improved performance and stability: Migrating to modern .NET delivers async/await efficiency, optimized memory management, faster startup times and access to performance-focused libraries that weren't available in legacy .NET Framework.
Enhanced security compliance: Modern .NET includes built-in protections against CSRF, XSS and SQL injection, supports TLS 1.3, integrates with Azure Key Vault/AWS Secrets Manager, and receives regular security patches—unlike end-of-life .NET Framework versions.
Minimal business disruption: We use phased migration strategies, feature flags, parallel running (old and new systems side-by-side), automated testing and careful rollout planning to ensure continuity during the transition.
.NET Migration Services We Offer
Application Refactoring & Architecture Upgrade
We refactor tightly coupled legacy code into clean, modular architectures using patterns like CQRS, repository pattern, dependency injection and domain-driven design—enabling easier testing, feature additions and long-term scalability.
Database & Integration Migration
We migrate SQL Server databases (schema, stored procedures, triggers), update Entity Framework/Dapper queries, refactor SOAP/WCF services to REST APIs, and re-integrate with CRM, ERP and payment gateways to ensure continued functionality after modernization.
Frequently Asked Questions
Find answers to common questions about our .NET Migration Services
No. Many migrations can be done incrementally, reusing existing logic while upgrading the platform and architecture.
Timelines depend on application size and complexity, but most migrations are completed in phased stages to reduce risk and downtime.
Our migration strategy minimizes user impact by ensuring backward compatibility and careful rollout planning.
Yes. We design migrations with cloud deployment, scalability, and CI/CD support in mind.
.NET Framework 4.5.2 and below are out of support. .NET Framework 4.6.2+ still receives security patches but no new features. Modern .NET (currently .NET 8/9) is the future with cross-platform support, performance improvements and active development.
Yes, incremental migration is often safer. We transfer one feature at a time to the new modern .NET while legacy features remain on .NET Framework until they're refactored—minimizing risk and allowing phased budget allocation.
Web Forms has no direct equivalent in modern .NET, so we typically migrate to ASP.NET Core MVC, Razor Pages or a React/Angular frontend.
Yes. We audit dependencies for .NET compatibility, replace incompatible packages with modern alternatives, and refactor custom integrations where needed.
