The process consists of the following important steps:
- Open your original catalog on the source computer and move the root folder of your images (using the method above) to the temporary location, e.g. external drive.
- Back up the original catalog to the temporary location that is used for the file transfer. Check the instruction here (starting from Step 5) https://support.captureone.com/hc/en-us/articles/360002520238
- Create the new catalog on the target computer and import the backed up original catalog from the temporary location. You should now be able to see all the images that were moved to the temporary location with their rating, adjustments, etc., and to move them anywhere on your target computer using the mentioned above method.
