Catalog Merge

[Heirloom Bob]

Edited my travel images on my laptop and once completed, exported as a catalog, to an external drive. Plugged the drive into my desktop to merge catalogs. process shows the images, edited and RAW but all images are "greyed" out and will not import.An I missing something here? Lightroom Classic 11.5 and Windows 10

With the Export with Catalog, did you use the option to export the 'negatives'?

[Heirloom Bob]

Good thought. I will export again.

Yes...I had selected Export Negative Files and Included available previews. Export in progress.

This works for me, YMMV: I clone (backup) my entire hard drive of photos, the catalog (one), presets etc to multiple drives. I take a clone on the road and work on that, adding images, editing, whatever. Then when I return, I clone that drive to the other(s), and only the new images, edits, etc are cloned back. It is fast, and it allows me to have access to all the other images on the road. Might be worth trying.

But the process as I spelled it out, is also supposed to do the job and it's what I have done in the past successfully.

[TheDigitalDog]

Yes, it should do the job; its just a lot more work, more documents to futz with without the benefit of another backup.

You haven't selected anything.  Check 'All Folders' in the top left corner...

[Heirloom Bob]

No option to Check "All Folders"

[JohanElzenga]

Those sure look like normal checkboxes to me... Have you tried the three folders individually?

BTW: Not exporting the negatives should not be the problem. In that case you can still import the new images, you just can't move them to another location because they are still linked to the original image location, which is 'missing'.
