Few months ago (may 5-6?) was a few thread some similar “location” stuffs - how to change path(s) / folders in the database directly. Example: vol01\photos → vol02\goodphotos and all subfolder in one data update.
I suggest to search for: Relocate folders that have been moved and Moving all images to an external drive - may its helps you out. With that it’s also can fix the “Project” part.
