VBUC generates native code without runtimes.

VB6 has been out of support for over a decade. The Visual Basic Upgrade Companion quickly and efficiently migrates VB6 code to C# or VB.NET and .NET Core or Framework with Windows Forms. Faster than a rewrite, more productive than all other solutions.

Unlike a rewrite, VBUC moves existing back-end logic to the new platform, keeping proven and debugged logic and processes intact and dramatically reducing the total defects to be resolved following the migration.

Accelerate application modernization

Automated migration reduces the time and cost to modernize existing desktop apps compared to rewriting from scratch.

AI-assisted algorithms produce native C# or VB.NET code with the .NET Framework/.NET Core for safe, performant, and familiar applications that can be deployed immediately. Applications as large as 3 million lines of code have been migrated fully in months, not years.

Mobilize.Net offers valuable technology and services that help customers easily modernize their legacy applications for use on today’s modern platforms and devices program at Microsoft.

- Shawn Nandi, Sr Director, Cloud App Development, Data & AI Marketing

We were able to migrate our VB6 code to .NET using the VBUC license we acquired through MSDN. After the migration only a few things needed manual modification. So your software did a great job and saved us a lot of time

- JMarco Botermans, Owner - Fluke

“Mobilize.Net has a strong track record of building products that successfully automate challenging source code migrations, and this [product] will empower our customers to get up and running on Snowflake sooner.”

- Chris Degnan, CRO at Snowflake

Mobilize.Net seemed the only one that sorted out the details, not only the basic issues of a migration engagement. Its product, the Visual Basic Upgrade Companion, included unique, powerful features, many of which turned out to be very valuable for this specific project, like ADO to ADO.NET conversion and error handling transformation

- Rod Coles – President, Bold Technologies, Ltd

We ran a proof of concept comparing the Visual Basic Upgrade Companion (VBUC) with other VB6 migration tools and we definitely preferred the way VBUC handled the conversion.
