Lightroom CC: Some Photos Invalid after migrating catalog from Lightroom 6.0

I have migrated my Lightroom 6.0 catalog to Lightroom CC. The originals are stored on NAS folder in line with official instructions and the option to "Store a copy of all originals in a specified locatoin" has been set before the catalog migration.
The migration has completed successfull and Lightroom CC has been busy with syncing the photos to the cloud. Unfortunatelly after syncing 34000 out of 54000 photos it has stopped the synchronization with an error message "Some Photos Invalid".
I've tried the solution provided in the adobe Known Issues DB (LINK) and in some other threads but without success.
Press Ctrl+A (Win) or Command+A (Mac) to select all the photos displaying in the grid and then do any of the following:- Delete the selected photos by choosing the Edit > Delete option and then add the photos in Lightroom CC again.- Apply a flag or a star rating to selected photos.

In case I take the second option to just change a flag or star rating the photo is synchronized but only the metadata, the original is still on local drive only (the NAS).
If I choose the second option the files are added successfully and synchronized to the cloud but I'm losing all edits performed on such photos. And it is very inconvenient for almost 20000 files, not even knowing in which folders they are located.

How can I fix this issue? If this is not resolved I don't see a point in continuing the CC subscription, now I can't even re-import the entire catalog as this can be only done once (not to mention that migration of 400GB in 54000 files is very time consuming even on a fiber channel internet connection.

Adam,

I don't really have enough information to go on.  Where were your Lightroom Classic CC catalog and images located prior to the attempt at migration into Lightroom CC?

It is possible to remigrate a catalog a couple of different ways. I would rather try and understand what went wrong the first time than just blindly try to remigrate.

Hi Rikk,

My set up Lightroom Classic CC catalog is located on an SSD drive on my PC. It also hosts LR Cache. Images are stored on NAS, normally I'm importing all RAW photos from my camera converting them to DNG format. As I shoot RAW+JPG LR is nicely keeping the pair of DNG and JPG of imported photos.

When migrating the catalog and photos to Lightroom CC I've configured LR to keep originals on the same NAS. The migration went ok so all my photos have been copied to the new originals folder and are visible in Lightroom CC for desktop application. Total number of imported photos was over 56000. 37000 were synchronized with the cloud and are now visible on any device or web app but 19000 of the photos have not synchronized with the error mentioned above.

Please let me know if you need any further details or technical information, logs etc.

Thanks for info. I'll wait another 2 weeks and will cancel my subscription as in this shape it does not work for me. Not to mention that the CC Desktop app is very slow anyway.

2.2 was released yesterday. Are you able to try again and see if the error still appears?

Well, I've cancelled my subscription as it was useless. Not sure if I have an energy to try again. Is there a way to try the migration process without paying the subscription again?

The trial should have reset with the 2.2 release. You should be able to use it for 7 days.

Will I be able to load large amount of files to the cloud as well?

Here is my experience after installation of the 2.2 release. I have not tried with the same LR6 catalog but I have split it into smaller chunks. I've migrated a catalog of over 11000 images and size of over 170GB and so far so good. Entire catalog was migrated and all photos synchronized to Adobe Cloud!
This is good news. I'll now give it a try with remaining catalogs to end up with my entire collection.

Apparently it was a bad idea to split the catalog. I have done this by making 2 additional copies of my original catalog and removed unnecessary files from all 3 catalogs (so I have now a catalog for photos until 2010, one for 2011-2015 and one for photos from 2016 till now). I have migrated the latest photos (2011-2019 catalog) successfully but I can't migrate the other 2 catalogs as apparently Ligtroom CC for Desktop recognizes them as the same catalog that I've already migrated. 
How can I solve this problem? Migrating the entire huge catalog at once is not my preferred option.

The better method is to divide your catalog into sections by creating a collection for each migration and calving the fragments into catalogs.  Here is an overview of the process.

  1. Create a collection called Migration 1
  2. Put a fraction of your files into this collection segregated by capture date or some other definitive identification method. (e.g Collections for: 2012 and older, 2013-2016, 2017 and newer) or however many you need to split it up into manageable chunks.
  3. Right-click on the collection and choose "Export this collection as a catalog"
  4. Migrate this created catalog from step 3
  5. Repeat for the next fraction.
This will create distinct versions of your catalog for migrating into Lightroom CC and avoid the issue you are seeing.  Rather than carve the elephant out of single block of stone - build it from smaller pieces.

Thanks for the suggestion. Will try it over the weekend and report back the result. One issue I was facing so far is that I could not export photos or folders to a new catalog, nothing was happening. When I've split the catalog into smaller ones for on it was working OK but not for another. Seems like if the catalog is too big the export as catalog feature does not work at all. Is that a known limitation?

I just tested on a 380,000 image catalog and it worked ok for me.
