Migration from centralized version control system to a distributed version control system

A system for migration from a centralized version control system to a distributed version control system, comprising:

• a processor and a memory configured to provide computer program instructions to the processor to execute a function of a plurality of components:
• an application defining component for defining a set of applications for an installation that is to be migrated from a centralized version control system, each application including a plurality of programs for executing tasks and associated program calls used to communicate between the programs;
• a plurality of distributed version control repositories for each of the applications;
• a code analysis component for analyzing a source code related to the installation, by accessing source code metadata and any related data structure files used by a plurality of programs associated with the source code;
• an include file analyzing component for identifying at least one include file associated with the analyzed source code analyzing an identified include file, wherein said include file analyzing component further determines if any include file has an associated single owning application;
• a classifying component for classifying a communication data structure as private, wherein a private classification denotes when a service providing program and a service consuming program belong to a same owning application;
• the classifying component classifying a communication data structure as a public include file when the service providing program and the service consuming program belong to different applications;
• and
• the classifying component classifying a communication data structure as a shared include file when the service providing program is used by more than one application or when a target program is not found through metadata, wherein, the include file classified as a shared include file is forwarded with the include file to the shared distributed version control repository;
• a dispatching component for sending any include files having the single owning application to a distributed version control repository for the owning application;
• and
• an executing component for migrating the set of applications for the installation from the centralized version control system for executing tasks and associated program calls for communication between the programs.

A computer program product for migration from a centralized version control system to a distributed version control system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• define a set of applications for an installation that is to be migrated from a centralized version control system, wherein each application includes a plurality of programs for executing tasks and associated program calls for communication between the programs;
• provide a plurality of distributed version control repositories for each of the applications;
• analyze a source code related to the installation, by accessing source code metadata and any related data structure files used by a plurality of programs associated with the source code;
• provide results of said source code being analyzed in a relational database;
• identifying at least one include file from said relational database based on file usage and associated collected results;
• determine for each include file identified whether there is a single owning application;
• determine when any include files have a communication data structure that is used as an interface between programs and any associated owning applications;
• determine if any include files are shared between more than one application when there is no identified owning application;
• classify any include file for the communication data structure as private when a service providing program and a service consuming program exist that belong to a same owning application;
• provide any include files that are shared between more than one application to a shared distributed version control repository, wherein for an identified include file for which a target program is not included in the accessed metadata, the include file is classified as a shared include file and a classification related to the communication data structure is forwarded with the include file to the shared distributed version control repository;
• provide any include file identified as having an owning application to a distributed version control repository of the owning application;
• and
• migrate the set of applications for the installation from the centralized version control system for executing tasks and associated program calls for communication between the programs.
