Unable to open old catalog

[schinigo]

I'm about to lose my freaking mind.  LRC forced me to upgrade my catalog, now I can't re-open my old one.  Do not have access to any of my work.  Please advise ASAP.  TIA

Sorry no answers, but the same thing happened to me. I'm gonna follow along here and hopefully get some answers too.

I've had the same, upgraded and catalog has become corrupted during/following reformatting. Opened the backup zip file created automatically prior to catalog reformatting and the same - file is corrupted.

Had to go and get my own backup from a week ago, open and  let it reformat etc and everything upto last week now restored - this was on my Windows 11 desktop - what a pain! My Mac upgraded ok, but  different and much smaller catalog.

Most major upgrades of Lightroom-Classic (eg. 13 > 14) require an upgrade of a catalog to work with the new LrC version.

A Catalog upgrade always leaves behind a copy of the old "Previous Version" catalog in a ZIP file that (If extracted from the ZIP) will remain compatible with the 'previous' version of LrC. You should have seen this dialog-

There is no reason to "open an old one" if the catalog upgrade worked correctly. All your edits and work will be in the upgraded catalog. 

It can happen rarely that the upgrade process uses the wrong catalog, or even creates a new empty catalog, but you will still have the earlier catalog version somewhere in your system.  (I experienced an empty catalog once, possibly because my catalogs are on an external drive.)

If you extract the catalog from the ZIP you can [Double-Click] the extracted .LRCAT file to once again do a successful catalog upgrade, OR-

If you insist on opening a previous version of a catalog, without a catalog upgrade,  you would need to downgrade Lr-Classic by installing the previous version from the Adobe Creative Cloud Desktop app that matches the Catalog version.

A  "Previous Version" catalog in a ZIP file would be found in the same parent folder as the upgraded catalog.

Note: Catalogs are not renamed when upgraded. (So you might see 'Catalog v13' working in Lr-Classic v14). Catalog renaming is now done from the menu in the app.

To both @schinigo and @sarabt98 , we need information if we are going to help you. And I think you should know that your old catalog is still out there on your hard disk, with all of your work in it. It hasn't disappeared or changed.

Why do you need the old catalog file? Please explain.

What happens when you try to re-open the old one? Explain in detail. If there is an error message, what is the exact word-for-word error message?

Hi there, When I open the book module( I had been creating a book), the photos are there, but when I go to the develop module they say these files are not available, or or I'm missing. I am not able to work on them. I know these files are on my external hard drive but even when I plug it in it doesn't seem to connect to the current book module with all those files that I can't work on. How do I connect the folder on my hard drive with the stored photos copies in lightroom?

@sarabt98  Please place your problem in a new thread, with complete explanation. This thread was started because someone else can't open their catalog, but you have obviously opened your catalog so it doesn't belong in this thread. People will be happy to help you in a new thread; but please don't discuss it any more in this thread.

I just upgraded my catalogs as mentioned here, but I forgot to have my external hard drive attached when doing so. Now Lightroom won't recognize my external hard drive catalogs because those catalogs didn't update. How can I update these catalogs?
