Do you mean move the catalog file itself to another disk? Or do you mean move the photos to another disk? Or both?
It looks like you moved the images to another disk, and then created a new catalog. By default, your catalog folder is a folder inside your 'Pictures' folder, but it is separate from the pictures themselves.
Check this out, it can be used to move to another disk as well: https://www.lightroomqueen.com/how-move-lightroom-to-new-computer/
I mean both
You probably can delete the catalog that is missing some folders.
First, you copy the catalog file to a new empty folder on the other hard disk, then double-click on it to open it in Lightroom. You can copy the photos to the new hard disk next (do not change the folder hierarchy or move photos from one folder to another), following the instructions in "Part 2 — Update Folder Location" in this document: Adobe Lightroom - Find moved or missing files and folders
