Moving a catalog with photos to an external SSD (workaround)
My internal 2TB SSD drive reached its limit at 60K images and so I had to swap out the catalog with all the source files. OWC Envoy Express Thunderbolt 3 NVMe SSD with a 4TB Crucial SSD on an Imac was the solution. Open the current catalog in C1 and add the new SSD in the folder (+). Now the entire source directories can simply be dragged step by step with the mouse from the original catalog to the SSD directory. C1 starts a transfer process and depending on how many images are in this directory, it can take some time. The source directory is automatically deleted and the new reference is then the external SSD.
The catalog can be copied to the new SSD or can remain on its old place. I moved both (photos and catalog) to the SSD and can use it on a Macbook.
The whole process took about 2 hours with a 60K library.
I didn't notice any noticeable loss of speed. Important is ,that if the catalog is used on another device, it must be closed (locked) from C1.

Sounds bulletproof as it can get. Some years ago, I moved my entire collection of reference RAW image files to a new larger external drive, but copied them using Finder. Of course Capture One had no idea of where they were until I renamed the new drive with the same name as the old drive. Capture One only checks the drive name and so this worked. Assuming copying from within Capture One works as fast as Finder and you can do without Capture One for a few hours, your way makes more sense. I would not call it a workaround.

Capture One checks more than the drive name. It checks every single file. On macOS the drive name becomes part of the full path to the file.
/Volumes/DRIVENAME/path/to/your/file.ext
This full path is stored in the catalog. Fixing the drive name also forces macOS to rename the mount folder name and thus the full path to the file. THAT makes the catalog happy.

Absolutely correct, of course, Walter. My point was very narrow. If you duplicate the referenced files with finder, mirroring the path structure on a drive recognized by Capture One, as long as the path structure is identical, Capture One will recognize the new drive as if it were the original drive as long as it has the same name as the original drive.
I have done this a few times when moving my referenced files to a new larger external drive.

Jerry C @... .. yes we all are correct. the key is keeping the original folder hierarchy. I too have done this many times as I graduated to larger and larger drives.
