I had an Aperture installation on an old iMac running OS X 10.13.6 High Sierra. The iMac no longer works, but I was able to remove the hard drive and to copy library and pictures .

The Aperture library is located in the directory

~/Pictures

The pictures are (as referenced pictures) in directories sorted by years/months/days also in the directory

~/Pictures

I have copied the Aperture Library and the entire directory structure with the images to a SSD and would now like to manage them with Lightroom on my MacBook Pro under OS X 14.6 Sonoma.

The Lightroom library is located under

~/Pictures

The images are referenced on an external SSD.

How should I proceed with Avalanche for Lightroom in this case? I have opened the Aperture Library on the SSD on a trial basis and get the error message that the paths to the images are not correct. I am grateful for any advice!

Many thanks in advance

Tom
