Method and system for automated refactoring of mainframe based batch systems to cloud native environment

A system for automated refactoring of mainframe based batch systems to a cloud native environment, the system comprises:

• a user interface for providing an application as an input, wherein the application comprises a plurality of components, and the application is present on the mainframe based batch systems;
• one or more hardware processors;
• a memory in communication with the one or more hardware processors, wherein the one or more first hardware processors are configured to execute programmed instructions stored in the one or more first memories, to:
• group the plurality of components to analyze relationships and dependency links between the plurality of the components of the mainframe based batch system;
• eliminate a plurality of technology dependent components present in the grouped plurality of components to create an expanded version of the plurality of components which mimics the mainframe based batch systems;
• create a proprietary language independent model (PLIM) using the expanded plurality of components, wherein the proprietary language independent model comprises information from the plurality of JCL components and a plurality of tags required for refactoring;
• identify a target technology on which the refactoring is going to be done on the cloud native environment;
• create a conversion of the application through externalized command based templates (ECBT), wherein the ECBT are aligned to the proprietary language independent model (PLIM) and the target technology;
• and
• combine externalized commands in the ECBTs with the proprietary language independent model, wherein the combining results in the refactoring of each of the plurality of JCL components to the target technology.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• providing, via a user interface, an application as an input, wherein the application comprises a plurality of components, and the application is present on the mainframe based batch systems;
• grouping, the plurality of components to analyze relationships and dependency links between the plurality of the components of the mainframe based batch system;
• eliminating, via the one or more hardware processors, a plurality of technology dependent components present in the grouped plurality of components to create an expanded version of the plurality of components which mimics the mainframe based batch systems;
• creating, via the one or more hardware processors, a proprietary language independent model (PLIM) using the expanded plurality of components, wherein the proprietary language independent model comprises information from the plurality of JCL components and a plurality of tags required for refactoring;
• identifying, via the one or more hardware processors, a target technology on which the refactoring is going to be done on the cloud native environment;
• creating, via the one or more hardware processors, a conversion of the application through externalized command based templates (ECBT), wherein the ECBT are aligned to the proprietary language independent model (PLIM) and the target technology;
• and
• combining, via the one or more hardware processors, externalized commands in the ECBTs with the proprietary language independent model, wherein the combining results in the refactoring of each of the plurality of JCL components to the target technology.
