Are you sure you are using the correct catalog?
Thank you, I was using a different catalog. I found the older one and the developed photo files were there. Now I just need to figure out how to successfully combine them.
Your situation is now this-
1. Current working catalog- Photos have no edits.
2. The 'old' catalog- has the Photos WITH edits.
The quick answer is to use the menu function "Import from another Catalog", but it is a little more complicated than simply this.
The process is fully detailed in this link- https://www.lightroomqueen.com/partial-restore-backup-catalog/
Where Lightroom Queen refers to a "Backup Catalog"- you read it as your 'Old' catalog.
The method selects the 'edited' photos in your 'old' catalog, chooses "Export as a Catalog" to a 'temporary' catalog, then in your current catalog- "Import from another catalog" selecting the 'temporary' catalog to merge in the edits.
DO NOT DO any Exporting or Importing of Photos/files!
