Migrating photos from Aperture to Photos

I was migrating 283.74 GB of photos from Aperture to Photos in anticipation of Catalina. During the migration, Aperture suddenly quit. So now, I've migrated 276.83 GB to photos. Is there any easy way to figure out which photos didn't migrate? Secondly, once I have successfully migrated all the photos, can I delete the Aperture Library as well as the Aperture App?

In a nutshell: No, Yes and Yes.


The only way to be sure is to visually check. However, for a lot of reasons, I would not be comparing the libraries by their 'weight' in gigabytes. There can always be variation in caches and so on. The number of items is a much better check.
