VAGen Modernization and Migration

Eliminate the Risk of Running on Unsupported VAGen Software

VAGen Modernization Solution

Migrate, transform and modernize your mission-critical mainframe and client/server applications to a distributed and scaleable Web, cloud and microservices architecture and platform using the most comprehensive modernization solution available in the marketplace today. Applications built in the legacy 4GL VisualAge Generator (VAGen) platform can now be migrated wholesale or incrementally to your target programming language and platform of choice.

This modernization solution guarantees functional equivalence and eliminates end-user retraining. It dramatically reduces risk, cost and failure inherent in a rewrite. Gain a massive market advantage by rapidly migrating your mainframe green-screen or your desktop GUI applications into a single-page architecture (SPA) using industry-leading “reactive” JavaScript Web Frameworks such as Angular, React, Vue, JQuery or Dojo, powered by industrial-strength Java EE or .NET application servers or open source, cross-platform Node.js back-ends.
