Legacyleap in Action
Technical Demo
Legacy modernization doesn’t have to take years of discovery and millions in risk. In this live demo, we’ll show you how Legacyleap autogenerates the artifacts, plans, and code transformations needed to compress months of manual work into days.

Drift detection, and more
With traditional methods, migrating a large VB6 application could take 6-12 months. Using Legacyleap, most projects are completed in 2-4 months end-to-end from code comprehension to deployment. Our platform automates up to 70% of the effort, including documentation, transformation, testing, and artifact generation, drastically accelerating timelines without compromising quality.
VB6 is no longer supported by Microsoft, which means increasing security vulnerabilities, compatibility issues, and a shrinking talent pool. The longer you delay, the more undocumented business logic is lost as maintainers leave. This raises migration costs and risks over time, especially for systems still running critical operations.
Yes. Legacyleap supports phased modernization. You can start with high-risk or high-value modules and modernize incrementally. The platform’s modular architecture enables partial transformation, seamless integration with legacy components, and rollback planning, giving you full control over modernization scope and pacing.
If your VB6 application is business-critical, hard to maintain, lacks documentation, or relies on deprecated dependencies, it’s ready. During our free $0 assessment, we analyze the source code for risks, architecture drift, API dependencies, and functional complexity so you know exactly what’s feasible, what’s risky, and what’s worth prioritizing.
Business continuity relies on a phased, well-governed approach. Critical workloads are migrated incrementally using strangler patterns and parallel environments to minimize disruption. AI-assisted impact analysis and automated testing ensure functional parity across versions, while rollback checkpoints and human-in-the-loop oversight preserve operational stability throughout the modernization cycle.
We’ll scan a portion of your legacy VB6 codebase and deliver export-ready functional and technical documentation, architecture maps, dependency graphs, and technical debt insights all in 3–5 days.
