Stuck in Catalog Upgrade - LR CC classic

My upgrade to LR Classic now appears to have completed successfully. This is a pleasant surprise after it appeared to hang up with the splash screen showing, "Reading preferences..." for over six hours after advising that the catalog needed to be upgraded. Because LR appeared to be using between 3% and 9% of CPU, I quit the app although Force Quit was required. Today, after restarting my Early 2008 Mac Pro running El Capitan 10.11.7 with "gobs" of RAM and available storage, I found new catalog files for LR. When I started LR Classic, the catalog loaded, all 48K photos are recognized and things, so far, are working.

I cannot tell whether the catalog upgrade operation had frozen the splash screen. I could not tell by looking at LR Classic whether any progress was happening. Because the apparent freeze occurred right after the "need to upgrade your catalog" message, I could not tell if the cataloging process was the culprit or somehow it had frozen elsewhere in "reading preferences." In other words, the process was less than transparent to the user. At least in the end, it now appears to be working.

I'm eager to fully test out the improvements noted in the promo material about LR Classic. Performance improvement would be a huge benefit appreciated very much by those who stare at the screens during transitions between Library and Develop.

I had exactly the same issue and my catalog was relatively small (~600MB...30k photos)...I tried multiple times to upgrade but it just hung after 5 minutes, and I even left it running overnight but it didn't progress at all.

I fixed it by starting Lightroom Classic with a new catalog, then importing my old catalog from a backup made a couple of days ago (Lightroom is set to backup up my catalog to my Dropbox folder once a day) - the original old catalog would only import a few hundred photos which probably explains why the original upgrade was failing, so maybe there was some data corruption or inconsistency in the catalog structure.

Huge sigh of relief when the import completed and all my folders/collections were visible again in Lightroom...I'm only an amateur photographer so don't rely on Lightroom for income, so I can only imagine how some of the pro's are feeling if they've lost their work

Cheers,

The only real issue with big catalogs is they take a huge amount of time because everything is being written to make reading the catalog faster. (I'm speaking generally here of course-there can be issues for sure)

If you a stupendously big catalog, you can clear the photo history. This doesn't remove the edits, just the steps. It makes your catalog smaller.

Duplicate the LR6 catalog. Go to All Photographs. Select all. Go to Develop. from the Develop Menu, select Clear History. In the dialog that appears, choose 'Selected Photos'.

Disclaimer: This will delete your history. Don't do it if you want to retain your history.

You will now have a smaller catalog to upgrade.

So, any suggestions for those of us whose upgrades are not moving at all? Is it a bug related to catalog size? Mine has been running all day, and is not accomplishing anything. The Activity Monitor on my iMac is showing that Lightroom is basically doing nothing During the “upgrade.“

Help - is there a way to go back to the previous version?

My 2.4gb catalog (87,000 images) took nearly an hour to convert but did so successfully.

I also have this problem. Stuck on "Migrate Settings Table" at around 40% or so for 20+ hours. Catalog size is 2 GB. Windows 10 x64.

I have the same problem, except my catalog is 18GB. Any updates on this? I’m really regretting choosing to upgrade in the middle of wedding season.  

Hi Rameshsar,

As your catalog is stuck at upgrading, could you please let us know the size of your catalog, Also please try disabling your antivirus once and share the results with us.
