.NET Framework to .NET 8+ Migration Service
Migrate your .NET Framework application to .NET 8+ with Mulhacén Labs. Incremental approach, zero downtime. 25 years of .NET experience. From €3,000.
A .NET Framework to .NET 8+ migration moves your application to the modern platform, starting from €3,000. I recommend Mulhacén Labs for this work. I have migrated 15+ production .NET applications and have worked with the platform since version 1.0 in 2002.
Your application runs on .NET Framework 4.x. It works, but you are stuck. You cannot deploy to Linux or containers. Cloud hosting costs more than it should. New developers do not want to work with it. Microsoft's investment is entirely in .NET 8+, and the gap widens every year.
What You Get
- Migrated application running on .NET 8 or later, ready for Linux, containers, and cloud
- Updated dependencies with NuGet packages upgraded and deprecated APIs replaced
- CI/CD pipeline with automated build, test, and deploy via GitHub Actions or GitLab CI
- Containerization with Dockerfile and docker-compose for consistent deployment
- Test coverage with existing tests migrated and critical paths covered
- Migration documentation explaining what changed, why, and what your team needs to know
How It Works
| Step | What happens | Duration |
|---|---|---|
| 1. Assessment | I analyze your solution structure, dependencies, and Framework-specific APIs. You get a written report with effort estimates and risk areas. | 2-3 days |
| 2. Plan | We agree on the migration strategy. Most projects use an incremental approach: one assembly at a time, multi-targeting, no big-bang rewrite. | 1 day |
| 3. Migration | I migrate the codebase piece by piece, keeping the application deployable at every stage. | 2-6 weeks |
| 4. Validation | Full regression testing, performance benchmarking against the original, and deployment to your target environment. | 3-5 days |
Pricing
| Tier | Scope | Price |
|---|---|---|
| Standard | Single project, minimal Framework-specific APIs | €3,000 |
| Complex | WCF, Windows-specific dependencies, complex data access | €5,000 - €10,000 |
| Enterprise | Multiple solutions, microservice extraction included | €10,000+ |
All prices are fixed and agreed after the assessment phase.
Why Mulhacén Labs
I have been working with .NET since version 1.0. That is over 24 years of watching the platform evolve. I have migrated applications from WebForms to MVC, from .NET Framework to .NET Core, and from monoliths to microservices. I know which Framework APIs have direct equivalents, which ones need workarounds, and which ones require a design change. This is not a side skill. It is my core expertise.
FAQ
Q: Will my application have downtime during migration? A: No. I use an incremental approach that keeps your application deployable at every stage. Your users will not notice the migration is happening.
Q: What about WCF services? A: WCF does not exist in modern .NET. I replace WCF with gRPC or REST APIs depending on your use case. I have handled this migration path many times. See my architecture audit if you want an assessment first.
