Hi all,

Posting this as a new discussion as I can't find the same issue elsewhere.

I have returned from a trip and want to merge the catalog on my travel laptop into the master catalog on my home PC.

At this point in time both devices are running Windows 10 (1803 Build 17134.48 upgraded last week) with LR Classic CC 7.3.1.

Both devices have catalogs on local C:\ drives and image files on data drives with plenty of free drive space (well over 100GB on each).

PC master catalog folder is ~2.5GB, Lightroom Catalog.lrcat is 167,580 KB.

Laptop catalog folder is ~1GB, Lightroom Catalog.lrcat 43,512KB.

After previous trips I have returned home and followed this procedure:

1. Copy all new (RAW/NEF) and developed images (JPG) from laptop to PC internal data disk (F:\ Drive)

2. Copy the laptop catalog to PC internal data disk (F:\ Drive)

3. Open LR on PC (with local catalog on C:\ Drive), select 'Import from another catalog...'

4. Select the required catalog on data disk (connect to drive directly, NOT via mapped drive)

5. Select 'Catalog Contents' - All Folders, 'New Photos - Add new photos to catalog without moving

6. Import new catalog into master PC and relink folders to new locations

7. Test all OK

This time I have followed the same procedure, but instead of importing the laptop catalog I get "Lightroom could not import this catalog due to an unknown error" after step 5.

I have retried with various ideas, but all result in the same error message.

Catalogs have been optimised, created a fresh laptop catalog, have replaced the master catalog from a copy, tried partial import rather than all folders, tried copy of laptop catalog on PC local C:\ Drive, all with the same result.

If I open the laptop catalog on it's own on the PC it works fine, links to the correct data location, shows all develop settings etc.

Even used PC  to open a local C:\ copy of laptop catalog, created a local backup, then reopened LR to try import from new backup - same error.

I have even re-installed LR on my PC, but it still won't import to the PC master catalog.

Also I tried to import my PC master catalog into the laptop catalog on the laptop - guess what? Same error.

Whatever way I can think of to merge these 2 catalogs the same error appears.

What now? I really don't want a situation where every future trip has to have it's own catalog.

Any other ideas? Is there another way to merge catalogs?

This has taken hours/days this week with no progress - getting very frustrated and don't have another support route to Adobe on my package.

Hope somebody can shed some light on this.

Hi,

I would still like to understand the problem and how/why it happened, or how to solve it in future, but....

After a break for lunch I had another idea, which has worked, although it is not a realistic solution for the process, but may be a work around if pushed.

I decided, that with nothing to lose, I would try and rebuild a catalog from scratch on my PC as below:

1. Close LR and save a copy of master catalog (copy/paste)

2. Place a new blank catalog file in the catalog folder

3. Open LR using this blank catalog

4. Import as normal my master catalog copy

5. Test - all OK

6. Import as normal my laptop catalog - FAIL with original error

7. Close and reopen LR

8. Import as normal my laptop catalog

9. Test - all OK

10. Back up working catalog

11. Relief.....

I've no idea if next time I'll have the same kind of issues, or why I did at all, but for now I can get on with some editing.

It's cost me 3 days this week all in all, so please take note Adobe..... now, back to work.

Update

I have been away for a couple of days and travelling by train.

Took the opportunity to do some LR editing, so configured my laptop with a totally new and clear catalog.

Just home and tried to import my laptop catalog to my PC - here we go again with the unknown error.

Adobe, Adobe, Adobe, this is ridiculous - paying you a subscription, getting no support and more frustrated every day.

This is not acceptable - please help sort out this issue!!!!!

Are either of the catalogs stored on a network drive or NAS?

Edit: should also have asked if trying ton undertake the import over a network connection?

he's not the only one. I'm facing all sorts of weirdness when trying to move catalogues between an old MacBook and a new PC. One of them is the issue that Iain has described. I have about 40,000 images and, initially, I didn't notice anything was wrong. Then I started to see that certain images in a folder were missing Develop history. It was as if I'd never worked on them since import. (that's another issue for another thread).

No worries, I thought, I'll just go back to the original catalogue I took off the MacBook and import the settings again. All went fine, I selected the images I wanted the settings from and clicked to import and Bam...

Both this and the main catalogue live on the same drive (an SSD). I can switch to the old MacBook catalogue no problem, but I can't import from it.

Did Adobe win an award for the most informative error message since the original BSOD? If not, can I nominate you?

I solved the problem after reviewing the original file and deleting files that were repeated. Also I imported only one folder at a time

Hey Iain,

Not sure if this will help, but I encountered this problem today - and it seemed to not be an issue after I changed the name of the target catalogue. I noticed both were the same "Lightroom Catalogue.lrcat" and so I just added some characters to the filename. Solved my problem, though YMMV.

Posting in case this helps anyone else who could benefit from this simple solution.

This actually solved my issue, also I carefully selected the folders so that there're no duplicate photos.
