If you imported images in directly without using a catalog upgrade, then yes, you won't see any metadata with the files unless you saved out the metadata from the file in the past. .
We did the catalog upgrade. It didn't see ANY of the prior folders or hard dives or even any of hte prior catalogs from LRv 5 (I think), so we began importing folders one by one. Stopped after the 3rd when I realized we were missing edits.
What is the workaround?
Can we downgrade the version?
If the catalog update didn't see anything, you most likely didn't use the right catalog file when upgrading. Have a look around for more .lrcat files on the drive. Look for larger files. This is what will most likely solve the issue.
If you're importing folders directly, then it's as if they were fresh new files.
