Lost Edits after updating Catalog to V12

[Harmonious_moments6C1B]

went from my old Computer ( 2013 Imac ) to a new M2 mac mini, transferred all pics and catalog into a hard drive, downloaded LRC in the new computer, when I clicked on the Catalog the first time  all folders transferred except one year ( 2022 ), not sure why, I synchronized everything and I was able to transferred 2022 but all the edits and changes are gone so not sure what to do. when I opened a previously edited pic there's nothing under history ( Develop Module ). I still have access to the old Imac and all the pics and edits are there with the old V11 version.   not sure what to do.

You have most likely opened the wrong catalog file. You need to search for the catalog that shows all of your photos and use that one.

yessss, thanks. Im an idiot, when im open the folder the food catalog was hidden at the bottom of the folder, the one on top was an older catalog.   Sorry about that
