System for verifying historical artifacts in disparate source control systems

A system comprising a computer processor, a computer-readable hardware storage medium, and program code embodied with the computer-readable hardware storage medium for execution by the computer processor to implement a method for verifying historical artifacts in disparate source control systems, comprising:

• obtaining historical artifacts from a target repository;
• obtaining historical artifacts from a source repository;
• verifying the historical artifacts in the target repository match the historical artifacts in the source repository, further comprising:
• comparing commit data in the historical artifacts in the target repository with commit data in the historical artifacts in the source repository;
• and
• evaluating whether each commit data event in the historical artifacts in the target repository is equivalent to a corresponding commit data event in the historical artifacts in the source repository, further comprising:
• logging a commit data event in the historical artifacts in the target repository which is not equivalent to a corresponding commit data event in the historical artifacts in the source repository;
• and
• reviewing the logging results;
• wherein:
• the metadata for the source repository and the target repository is in a standardized format;
• commit data comprises:
• commit changes, comments, authorship information, metadata and timestamps;
• a tolerance is established by a user for evaluating the commit data in the target and source repositories;
• the tolerance is a maximum number of differences between a commit data event in the historical artifacts in the target repository and a corresponding commit data event in the historical artifacts in the source repository;
• and
• each commit data event logged has a number of differences greater than the tolerance.
