Legacy modernisation · VB6

Convert Visual Basic 6 applications to .NET 8, de-risked by AI.

VB6 tools still run mission-critical work behind many corporate firewalls. Paradym Next reads the forms, modules and COM components, recovers the business logic and rebuilds it on .NET 8: in months, with your engineers approving every stage.

The problem

The VB6 tools your teams rely on are running on borrowed time.

Microsoft ended support for the VB6 development environment in 2008. The applications built with it keep working, but every Windows upgrade, security review and new hire makes them harder to keep.

Unsupported tooling

The IDE and many third-party controls are out of support, so fixes and upgrades are increasingly risky.

COM and desktop dependencies

Registered components and per-desktop installs block cloud hosting and remote working.

Few developers left

Engineers who can confidently change VB6 code are hard to find.

Hidden business rules

Business rules sit in button click handlers, modules and COM classes written by people who have long since moved on. Finding and documenting them is how a .NET rebuild keeps the behaviour your teams depend on.

How it works

How our AI-powered modernisation engine works.

Four stages take your VB6 application from undocumented code to .NET 8. AI agents do the reading, mapping, writing and testing. Your engineers approve every stage.

01

Automated discovery and code parsing

Next parses your VB6 forms, modules, classes, COM components and ADO data access and extracts the business rules, data flows and integrations inside them. Every rule is traced to the code it came from, so nothing drifts in translation.

02

AI-assisted architecture blueprint

Agents map each module to clean target patterns: .NET 8 applications and services, Web APIs and managed SQL databases. Your architects review and approve the blueprint before any code is written.

03

Automated refactoring

From the approved blueprint, Next generates production-ready code for .NET 8. It consolidates duplicated logic and removes dead code, and your engineers review every change.

04

AI-driven regression testing and validation

Generated test suites run the old and new systems on the same inputs, validating 99% functional equivalence before deployment. Any difference goes to your team to resolve.

Value acceleration

What AI acceleration changes.

Compared with a standard manual migration of your VB6 application.

Up to 40%

less development effort than a standard manual migration.

3–4x

faster upgrade and migration cycles.

Up to 60%

lower operational and cloud infrastructure overhead.

Risk and accuracy

AI does the heavy lifting. Your engineers make the decisions.

For a CTO or CIO, the risk in a rewrite is not speed but correctness. Human review is built into every stage, so AI output never reaches production unchecked.

Traced to source

Every extracted rule and generated module links back to the VB6 code it came from, so reviewers can check it line by line.

Human approval gates

Discovery, blueprint, code and release each need sign-off from your people. Nothing moves forward on AI output alone.

Equivalence testing

Old and new systems run the same test cases side by side, validated to 99% functional equivalence before deployment.

Governed AI

You choose which models are used and where they run, and every agent action is recorded for audit.
