The Character Copy button is present in the current PTR build and characters from your retail account are listed, but we're still working to get the copy process finalized so you'll likely run into "Copy Failed" errors.

We're working on resolving this but I don't have a current ETA to provide. I'll provide updates as we continue work on this.
