Catch-up feature and Versions Manager service allow to import new versions of the same Codebase and to automatically detect all impacts on the original Codebase project. Typically, when customers share with you a new version of the legacy source code (e.g. missing programs, new features, bug fixes, etc.).
AWS Blu Insights will automatically compare the two codebases and mention the new files, the deleted files and the changed files. In the same way, it lists all impacted workpackages, test scenarios, launched analysis, etc.
