Issues with merging photo libraries

[Qwerty11]

I have decided to try photos out instead of aperture. I apparamtly have two libraries. One for aperture and one for iphotos. I tried to import the iphoto library to aperture, but it said it had to be upgraded to the newest iphoto format, which was only possible through launching it in the new photos app. I did this and it loaded the iphotos library. The problem is that I am now unable to select the library in aperture and import. It is greyed out.

TL;DR I need help to combine multiple iphoto and aperture libraries into one.

my hunch is that Aperture can't import a Photos library. What you need is the final version of iPhoto to upgrade your iPhoto library to a version compatible with Aperture, then import that into Aperture.

As long as you haven't deleted the original iPhoto library, you should still be able to do it, my understanding of the process is that the Photos library is using the same files, but with a new metadata library for storing adjustment versions etc.

Getting the latest version of iPhoto might be the tricky part.

Couple of other options, one assumes you don't edit much, another assumes you have fast internet.

Export all one library as either versions or originals then open the other library in photos and import the image files.

Or

Open the smaller photos library, enable iCloud photos library, let it all upload then open the other photos library, change it to be the system library and enable iCloud library, and enable download originals. Then let it all download, you can then either keep your iCloud library or turn it off and use as a standard offline library. This way preserves the edits as non-destructive edits.
