AUTOMATED REFACTORING

VAGen Migration

Our Automated VisualAge Generator (VAGen) Refactoring solution delivers modern Cloud-enabled applications and databases that are functionally equivalent to their legacy counterparts, eliminating the hassle and expense of VAGen and the mainframe. This reduces cost, allows for deeper integration, and enables customisation to meet business requirements.

Why modernise?

CHALLENGES

Scarcity of domain expertise

Developers who understand VAGen and mainframe technology are reaching retirement age and no one is being trained to replace them, resulting in a steadily diminishing talent pool. As this shortage grows, the costs and risk of relying on VAGen will continue to rise.

Exorbitant costs

Mainframes running VAGen cost as much as 4,500 per cent more to operate than equivalent Cloud counterparts. This quandary is compounded by VAGen's rising maintenance fees.

Limited flexibility

Companies are rapidly moving to modern environments and practises such as DevOps and the Cloud. VAGen and the underlying systems that support it were not designed for modern IT, resulting in difficult integrations and limited flexibility.

Automated VAGen Refactoring

OUR SOLUTION

Our Automated VAGen Refactoring solution preserves the benefits of legacy systems whilst empowering organisations to leverage the advantages of newer platforms, especially the Cloud. This unlocks a whole new world of quality and scalability from automated testing, to quality assurance, and the ability to leverage containerised deployments and orchestration with Docker and Kubernetes.

This solution automatically refactors existing VAGen applications to fully maintainable Java or C#, whilst our modernisation methodology ensures the resulting code is compact, clean, and easy to maintain.

After go-live, Java and C# developers can extend application functionality for Cloud optimisation using standard DevOps tools and CI/CD concepts that simply aren’t available for mainframe applications. Object-oriented application architectures conform to web-centric requirements and will run on any Java application server (i.e. WebSphere, WebLogic, Apache Tomcat, etc.) or on Microsoft IIS when the target language is C#. Precious business logic from the legacy system is preserved, whilst levels of optimisation can be applied to deliver efficiencies and business benefits such as elasticity, granular service definition, and easy integration with Cloud-native services.

Refactoring a fourth-generation language like VAGen to object-oriented Java or C# presents many challenges. As such, our Automated VAGen Refactoring process was designed with the following requirements in mind:

  • Refactored applications must remain functionally equivalent to their original counterparts
  • Refactored applications must be easily maintainable, attain SonarQube A ratings, and follow object-oriented concepts and paradigms
  • Refactored applications should perform as well as, or better than, the original applications
  • Refactored applications should be Cloud-ready and delivered using a standard DevOps toolchain and best practices
