Still running your business on an old ASP.NET application?
We modernize legacy .NET applications — Web Forms, MVC, WCF, .NET Framework — to .NET 10 without starting from scratch, without shutting down your operation, and without throwing away the business logic it took years to build.
We've worked with .NET since its beta releases. Today we maintain ASP.NET MVC applications in production for clients who've been with us for more than a decade.
Signs it's time
If you recognize two or more, the system is already costing you more than it looks.
Nobody wants to touch the code
Every small change takes weeks because nobody's sure what will break. The person who understood it is gone.
It only runs on one specific server
It depends on a Windows Server, IIS setup, or SQL Server version nobody dares to upgrade.
Integrating anything new is impossible
Connecting payments, a CRM, or a mobile app turns into a huge project because the system exposes no APIs.
Security and compliance at risk
Unsupported components, no patches, no audit trail. A security or compliance review will flag it.
What we modernize
You don't always need a rewrite. Sometimes an incremental upgrade is enough; the audit decides what makes sense.
ASP.NET Web Forms → Blazor
Web Forms doesn't exist in modern .NET. We move it to Blazor (Server, WebAssembly, or Auto), keeping a component model your team already understands.
ASP.NET MVC 5 → ASP.NET Core
Controllers, views, authentication, and dependencies migrated to ASP.NET Core on .NET 10.
WCF and SOAP services → modern APIs
Services exposed as Web API or gRPC, documented and ready to integrate with other systems.
Entity Framework 6 and SQL Server
Migration to EF Core and an upgrade to a supported SQL Server version, or Azure SQL, with data validation before cutover.
From your own server to the cloud, if it pays off
Containers, Azure, or AWS when they cut cost or risk. If your current server works well, we won't push you to move.
Security and observability
Modern authentication, secrets out of the code, logging, and monitoring: what legacy systems almost never have.
How we migrate without stopping your business
In phases: the old and new systems run side by side until each module is proven.
-
Step 1
Audit of the current system
Inventory of modules, dependencies, versions, business logic, and security risks. This is where we decide whether to upgrade, rewrite, or combine.
-
Step 2
Phased migration plan
Prioritized by risk and value. Every phase has scope, price, and date in writing.
-
Step 3
Module-by-module migration
The new system gradually replaces the old one, with automated tests comparing results between both.
-
Step 4
Cutover and support
A planned final switch outside peak hours, with a rollback plan if anything fails, and ongoing support afterward.
Twenty years in .NET, not a recent course
We started with Visual Basic 5 and have worked with .NET since its betas. We've lived through Web Forms, MVC, WCF, and every SQL Server release, and we know where business logic hides in a 15-year-old system.
- MLM platforms in production
- Collections and law firm CRMs
- Accounting systems and banking integrations
- Medical records and property management
How we get started
A badly planned migration costs more than the old system. That's why we start by understanding what you have before quoting what to build.
Frequently asked questions
Do we have to rewrite everything from scratch?
Almost never. Most migrations happen in parts, keeping the business logic and replacing modules one at a time. A full rewrite only makes sense when the system is small or its logic no longer reflects how the business runs.
Will our operations stop during the migration?
No. Your current system keeps running while we build the new one in phases. The final cutover is scheduled outside peak hours, with a rollback plan.
How long does a modernization take?
It depends on the size and state of the system. A mid-sized application typically takes 2 to 6 months in phases. Discovery gives you a fixed timeline before you sign.
What if we have no documentation and the original developer is gone?
That's the most common case. The audit and discovery reconstruct how the system works from the code, the database, and interviews with the people who use it.
What about SQL Server 2016 or older?
SQL Server 2016 stopped receiving free security patches on July 14, 2026; only paid, temporary Extended Security Updates remain. We plan the upgrade to a supported version or Azure SQL as part of the modernization.
