![mainframe automated refactoring to aws]()
Automated Refactoring
Automated Refactoring with Advanced provides a turnkey modernization 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 optimization 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 containerized 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 AWS 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 a modern, distributed platform in AWS, 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 Optimization solutions are for customers who want to keep mainframe applications, reduce costs, and extend their capabilities to support new business requirements. Our modernization team leverages a combination of software built to automate optimizations and decades of mainframe expertise to maximize 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 reduce costs and maximize IT performance. Our Application Consolidation solution leverages our Automated Refactoring technology to transform relatively obscure languages such as Natural, CA Telon, Assembler, and PL/I to a common COBOL dialect. This reduces the complexity and footprint of your mainframe source code. Our solution also decreases costs by eliminating licensing fees and reducing risks associated with a shrinking talent pool capable of maintaining these less-common languages.
- 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, standardized change tailored to your specific needs.

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