I tried this on 3 different servers, on a total of 7 different WP installs. (Cpanel, plesk and godaddy)
From cpanel to cpanel I managed to get the entire clone process to work. The other 2 servers would not perform the database clone. The screen would flash, then quit. When i checked the database, there were no tables or information.
