![mainframe automated refactoring to aws]()
Automated Refactoring
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 AWS so you can retire the mainframe.
Once the legacy applications and databases are refactored, developers can extend application functionality 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.
Automated Refactoring is available for most languages, databases, and platforms, including z/OS, OpenVMS, and VME. -

Rehosting
You can retain your mainframe application code as-is while taking advantage of the cost savings and infinite elasticity of the Cloud by rehosting your legacy estate with Advanced.
Rehosting, sometimes referred to as replatforming, is ideal for companies whose applications are still meeting their business needs, and who therefore wish to retain their core application development skills while moving away from non-relational databases and expensive mainframe infrastructure. With rehosting, application source code is migrated onto modern, distributed platforms, either on-premises or in the Cloud, without change. Underlying legacy databases are migrated to relational models, configured to seamlessly interact with your applications via the rehosting platform.
Our Rehosting solutions leverage three key service activities to account for the application source code, data and supporting operational infrastructure:
- Application migration
- Data migration
- Platform deployment

Retaining
Our Portfolio Optimisation solutions are for customers who want to keep mainframe applications, reduce costs, and extend their capabilities to support new business requirements. Our modernisation team leverages a combination of software built to automate optimisations and decades of mainframe expertise to maximise your return on investment (ROI) and business value while retaining the mainframe.
Our solutions are as follows:
- Application Consolidation: Companies are rapidly consolidating their technology stacks to maximise IT performance. Whether the intent is to reduce licensing costs, simplify development cycles, or prepare for a rehost, Application Consolidation can act as a force multiplier in this process. Leveraging our Automated Refactoring solutions, we can consolidate disparate application languages into a single, optimised language. For example, languages such as CA Telon or Natural, which are intermingled with COBOL on the mainframe, can be consolidated to COBOL, eliminating licensing fees and simplifying maintenance of your application.
- Data Replication: Our Data Replication solution allows you to liberate non-relational data without a migration. Data is often trapped in non-relational databases such as IDMS that don't integrate with modern data warehouses. This solution empowers true business intelligence by integrating these non-relational databases with relational data warehouses using our replication software without disturbing IT or end users.
- Field Expansion: Over time, data standards have been implemented and mixed across applications and databases, making change of any kind risky. Our Field Expansion solution reaches across the millions of lines of code that comprise your applications, both online and batch. It locates all field elements and group levels that might ever hold the data contained in an expanding field or column. Then, regardless of each field name, data type or current length, it applies controlled, standardised change tailored to your specific needs.

Rewriting
Our Modernisation Platform as a Service (ModPaaS) is a purpose-built, customisable Cloud solution that enables highly collaborative participation throughout the journey of a legacy modernisation project. ModPaaS provides access to our modernisation solutions 'as a service' in a secure, Cloud-based environment. It also allows you to move through the modernisation journey at your own pace in a completely self-service manner, with assistance from our modernisation specialists, or with a fully-managed disposition.
ModPaaS is available for customers seeking to analyse mainframe code, and to understand inter-relationships, complexity, dependencies, and business rules. These are essential components to successfully plan for any modernisation project.

Retiring
Our Automated Archiving solution allows you to retain and access archived data and application source code by migrating these assets to repositories on modern, distributed systems. This removes the crippling cost of retaining the original mainframe infrastructure.
