After installing the Aperture 3, if you allow it to upgrade your existing library to newer database structure, it may take so long time. Your system may freeze halfway and you need to shut it down in an improper way, by holding the power button. At the same time, the performance of your system may decrease dramatically. The application avails all system resources and make it difficult to run other applications.

The above behavior needs you to close the Aperture 3 application. After that, when you check out the library of your Aperture 2, older library, you may find out that some or all of the pictures are missing.

Resolution

You can try using the Aperture Library First Aid to sort out the problem. It helps you to Repair permissions, Rebuild Database, or Repair Database. In case the photos are deleted, this option cannot help you to work around the problem.
