Automated Refactoring

Our Automated Refactoring solution delivers modern, Cloud-enabled applications and databases that are functionally equivalent to their legacy counterparts, eliminating the hassle and expense of the mainframe. This reduces cost, allows for deeper integration, and enables customisation to meet business requirements. This solution is great for moving legacy applications to Cloud-native languages such as Java and C#, and legacy databases to relational models.

Why modernise?


Scarcity of domain expertise

Developers and database administrators who understand mainframe technology are reaching retirement age, resulting in a steadily diminishing talent pool. As this shortage grows, the costs and risks of relying on legacy languages and databases will continue to rise.

Limited flexibility

Companies are rapidly moving to modern environments and practices such as DevOps and the cloud, while mainframes and the languages and databases that support them were not designed for modern IT, resulting in difficult integrations and limited flexibility.

Exorbitant costs

Mainframes cost as much as 4,500 per cent more to operate than equivalent cloud counterparts, a figure compounded by a scarcity of development resources and rising licensing and maintenance fees for ancillary mainframe utilities, applications, and databases. 

Automated Refactoring


To thrive in today's digital world, organisations must develop a mastery of rapid response, effortless course correction, and unencumbered agility in the face of competitive innovation. This is particularly difficult for large firms with rich heritage because of their reliance on outdated, inflexible IT systems such as mainframes. These mission-critical systems are expensive to run and contain unique intellectual property and business processes developed over decades, rendering them difficult to replace by traditional means.

Automated refactoring with Advanced provides a turnkey modernisation of your procedural codebase (or 4GL) to object-oriented Java or C# and your non-relational database to a relational model deployed to the cloud or in open systems on premises so you can retire the mainframe.

Once the legacy applications and databases are refactored, developers can extend application functionality for cloud optimisation using standard DevOps tools and CI/CD concepts that simply aren’t available for mainframe applications. Precious business logic from the legacy system is preserved, while 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.

Automated Refactoring with Advanced 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.

Many code transformation solutions create structurally similar programs in the target language, but require additional re-engineering efforts to yield desired results. Our solution is completely automated, removing the risk associated with the post-refactoring tweaks that go into other offerings.

Refactoring a 4GL or procedural language to object-oriented Java or C# presents many challenges. As such, Advanced's automated 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

Automated Refactoring is available for most languages, databases, and platforms, including z/OS, OpenVMS, and VME.
