VB6 Replacement: Migrate from Visual Basic 6 to modern platforms

We help you replace VB6 applications with modern solutions – step by step, with controlled risk and minimal disruption.

VB6 Replacement

Why replace VB6

Visual Basic 6 is no longer supported by Microsoft and runs on outdated infrastructure. Replacing it reduces security and compatibility risks and allows you to use modern tools and platforms. We migrate VB6 applications to .NET (C#, WinForms or WPF), web applications or hybrid setups – depending on your needs. We can do it incrementally (e.g. module by module) so operations continue during the transition.

  • Migration to .NET (C#, WinForms, WPF)
  • Web-based replacement where appropriate
  • Incremental migration to reduce risk
  • Data and business logic migration
  • Training and documentation

How we approach VB6 replacement

Replacing Visual Basic 6 applications does not have to mean a big-bang rewrite. We analyse your existing VB6 code and business logic, then propose a migration path: often module-by-module migration to .NET (C#, WinForms or WPF) so operations continue during the transition. Where a web-based replacement makes more sense – for remote access, multi-site use or future flexibility – we build a modern web app that replicates the critical workflows and integrates with your existing data and systems. Business logic is preserved and tested; only the UI and technology stack change. That keeps risk and cost under control and gives you a clear roadmap with milestones.

We have migrated dozens of VB6 applications for manufacturing, logistics and administration. Data migration, user training and documentation are part of our standard scope. After go-live we offer maintenance and further development so your new system evolves with your business. If you are unsure whether to migrate or replace, we provide an honest assessment: we recommend the option that fits your budget, timeline and long-term goals.

Frequently Asked Questions

VB6 Replacement

Migration & Timeline

Do we need a full rewrite?

Not necessarily. We often migrate module by module to .NET so operations continue. We analyse your VB6 app and recommend the most cost-effective path – refactor, re-platform or targeted rewrite.

How long does VB6 migration take?

Depends on size and approach. Smaller apps often 3–6 months; large systems 12–24 months or more. We give a realistic estimate after a short assessment.

Can we keep working during the migration?

Yes. During testing the old system keeps running. At go-live we plan a short cutover; we document and support so your team can adapt.

What about our data and interfaces?

We migrate databases and interfaces into the new architecture. Data continuity and clear documentation are part of our standard delivery.
