Our Automated Refactoring solution delivers modern, Cloud-enabled applications and databases that are functionally equivalent to their legacy counterparts. This reduces cost, allows for deeper integration, and enables customisation to meet business requirements. This solution is great for moving legacy mainframe applications to Cloud-native languages such as Java and C#, and legacy databases to relational models.
Automated Refactoring
Why modernise?
CHALLENGES
Scarcity of domain expertise
Developers and database administrators who understand legacy mainframe technology are reaching retirement age, resulting in a steadily diminishing talent pool. As this shortage grows, the costs and risks of relying on their languages and databases will continue to rise.
Limited flexibility
Companies are now leveraging 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, often 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
OUR SOLUTION
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 inflexible IT systems such as legacy mainframes. These mission-critical systems are increasingly 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.
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 legacy 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 IBM z/OS, OpenVMS, and VME.

OUR PROCESS
-
Step 1: Discovery
We begin every modernisation initiative with a discovery, free of charge. Our modernisation experts work with you to understand and document your business and technical goals and objectives. Together, we gather information about the mainframe estate. Everything from infrastructure to language and database types and quantities are accounted for. The discovery concludes with a workshop where we recommend optimal modernisation approaches based on information gathered, as well as rough order of magnitude (ROM) pricing, and estimated project durations and resource requirements.
-
Step 2: Assess and Design
The assess and design phase is performed using our automated tools to fully catalogue and develop a complete understanding of the application, infrastructure, and operational components of a mainframe environment. It exposes mainframe artefacts that organisations did not know they had, relationships that they did not realise existed, and assets that are no longer in use. Assess and design activities provide stakeholders with valuable insight to inform application modernisation decisions such as disposition strategies and target environment architectures. It also mitigates cost and risk by highlighting potential challenges and how to overcome them. At the conclusion of the assess and design phase, all in-scope artefacts are accounted for, a detailed project plan is established, and the transformation process begins.
-
Step 3: Transform
The transform phase includes the bulk of refactoring activities, the database and data modernisation, and build-out of the target operating environment. During transform, we refactor pre-defined work packets, perform functional tests, and deliver them into the DevOps pipeline. Whilst customer teams build, test, and deploy these work packets in the target environment, we refactor the next work packet, iterating until the entire mainframe estate has been transformed.
-
Step 4: Test & Deploy
The test and deploy phase begins with the receipt of work packets through the DevOps toolchain as they are delivered from iterative refactoring activities in the transform phase. If issues arise, the work packet is passed back to us where we review the code, adjust our tooling, reprocess the work packet, and send it back into the DevOps pipeline to resume testing and deployment. This process repeats until the entire modernised estate has been deployed. Our Automated Testing solution speeds this process significantly.
Prior to go-live, we refresh the target ecosystem by transforming a final snapshot of the mainframe environment to account for changes that have taken place throughout the modernisation project as part of normal business operations. Fortunately, since all adjustments and optimisations have been made to the automated tools and not the modernised code, this final refresh can be delivered into production over a weekend, eliminating code freezes.
-
Step 5: Support
We work closely with your team to ensure a smooth transition into production. Part of this transition includes the co-operative construction and testing of a go-live production cutover plan to reduce the potential risks associated with application deployments. We also provide on-demand assistance during the warranty period following production deployment, as well as appropriate rehosting platform support, and post-transformation support of the modernised applications.
"Advanced worked closely with our teams from the inception of the project through the sizing and planning to the delivery. The project has been completed within timescale and budget and this enables us to move onto the next stage of our IT strategy."
