How I plan to test my Aperture Library against Sierra

It’s almost time for me to move to macOS Sierra, now that the usual post-release beta testing is drawing to a close.

This is what I am doing to test my Aperture Library on Sierra:

1. Export a small Project as a Library.
2. Open the small Project and delete its contents. Now it’s an empty shell with my settings in it.
3. Import my existing Library into it. So everything is written with the latest version of Aperture.
4. Test with #3.

Apple Discussions have lots of fix and workaround suggestions for early Sierra, but I’m told they are no longer necessary. The things broken in El Capitan and broken in Sierra, but nothing new.
