I used the copy multiple accounts tool and it copied over almost half (9 accounts, around 25GB total). It failed on the other half (some as large as 15GB, others only a few MB), so I tried the process again. No matter what I do, I keep getting basically the same error:
The password is correct. I can login to WHM and SSH just fine on the old server, and this system worked to copy the first half of my sites. I tried changing my password on the old server and that did not help. I tried creating public keys on both servers and using that option, but it still gives the same error. Why is it still giving an error about the password when I'm using public keys? What can I do to fix this? One of the main reasons I'm even paying for cPanel on this new server was to make the transfer nice and easy, but so far it's done the exact opposite.
