Q: Aperture migrate file

Have a bunch of .migrateaplibrary files left after switching from Aperture to the Photos App. Have fully changed over to Photos App. Is there any reason to keep the .magrateaplibrary files? Are they redundant at this point? These total nearly a TB all together!

    If you have thoroughly tested the new Photos Library and are sure, that you need no longer to open the Aperture library to finish books, or to look up missing metadata or similar, then you can delete the Aperture Library.migrated.  But better keep a backup copy on a external drive, just in case.

     

    You will not gain much storage back by deleting the Aperture Library, however.  The photos in your Aperture Library and in the new Photos Library are using the same entries in the file table. Your Photos library uses hard links to the original photos in the Aperture library. This way, it looks like you would be needing twice the storage for apparent duplicates, but the photos in both libraries are stored on the same place on your drive. The storage will only be freed, if you delete a photo in both libraries.

    See:   Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support

    and: Six Colors: The (hard) link between Photos and iPhoto

     

    So delete the Aperture library only, if you are very sure, that you will not need it any longer.
