My HD got too small for my photo files, so I copied everything from my 4TB drive to the new 6TB drive. Everything ported over except my virtual copies, which is where I do most of my edits. How do I get my virtual files and edits over to the new drive so I don't have to keep this 4TB drive online?
Virtual copies do not exist as disk files. They are metadata copies within the catalog. You would have to have moved everything using Lightroom. But even then I'm not sure if your virtual copies would stay with their master counterparts.
So you have the files in two places now right???
Easy right click the top level Folders in the Library, select Update Folder Location and navigate to the Folder on the new drive. You will lose nothing. If you have reimported for some reason you will need to go back to an earlier back up catalog and use that to do what I have stated earlier.
