Migration Failed - Not allowing me to Migrate Again

[JCrossonNYC]

Migrated my Lightroom Classic Catalog. The migration assistant said that it was Successful, but all photos are missing from Lightroom CC. I am assuming it has something to do with the "Develop setting not migrated." There are no photos in Lightroom CC after migration except the ones that were already synced to Lightroom Mobile from Lightroom Classic (and those are just the previews, not the full RAW). Additionally, it won't let me migrate the catalog again.

I referred to the Help documentation; all files are available in Lightroom Classic CC (except for the 100 referenced below, out of 50,000) so this is not an issue with an external drive being disconnected or anything to that end. Lightrooom Classic CC functions normally for me so I'm not sure what could be wrong with the Catalog.

The software is useless without this working. Any help would be greatly appreciated.

Hi JCrossonNYC,

You may try renaming the Lightroom Classic CC catalog to something else and check if Lightroom CC let you migrate the catalog.

Also, checkout the below troubleshooting articles and let us know if that helps.

Hi,

This was not a helpful answer at all. I renamed my Lightroom Catalog as recommended but Lightroom CC still gives me the error message that the Catalog was already migrated.

I checked Possible Errors and the Migration steps before posting to the forum.

Rename does not work.

Hello. I have used Lightroom 4 then 6 since 2014. I had no choice but to purchase the cloud plan, and I chose the plan listed here for the 20gb photography plan: https://www.adobe.com/creativecloud/photography/compare-plans.html. 

However, the migration of my ".lrcat" file failed. I didn't do this step recommended by a well respected power user (LightroomQueen site). She wrote: "Lightroom Classic, Lightroom CC 2015 or Lightroom 6. If you’re migrating from an earlier Lightroom version (1.0-5.7.1), you must first install a trial of Lightroom Classic and allow it to upgrade a copy of your catalog to Lightroom Classic format before running migration." I failed to do that and then attempted to update the ".lrcat" file to my external drive where I had it (I always kept it on an external drive). I realized my error too late. So I failed because the catalog was trying to import way too much data beyond my 20gb limit. I then did these steps:

-I deleted all files from my Adobe account and then uninstalled Lightroom/LRC/PhotoShop/Creative Cloud app that all come with this plan.

-When I reimported those apps and started over, the reinstalled Lightroom Classic remembered my past effort and is preventing me from trying to do a fresh update (locally to my external drive, not to the cloud).

-Is there any trick you know to "try again"? 

If I can't fix this, I've lost 7 years worth of data (because I don't plan to buy more storage from Adobe). I realize this forum dates from 2018, but I tried the other Adobe forum sites and they are read only--I'll welcome any suggestion at this point. Thanks.

Exact same problem for me, I even tried twice after recreating a enw catalog and moving files on a new drive.  Same result. Could the fact that my Classic CC is expired cause this?

This is what I am getting in the log file (46539 of those...):

  Develop setting not migrated for 46539 Asset(s)

I found out how to migrate finally:

1. Go to LR Web and find Account Infos

2. Delete library

3. Close and restart LR CC Desktop

4. Start migation again
