You can use migration wizard from MySQL Workbench. Just choose the same local connection in both source and target selection, then change schema name on manual editing step. If nothing appears on manual editing step click next and the source and targets will appear. Click slowly on the source database name and edit to the correct name. Go thorough to the end and voilà – you have two identical databases with different names. Note you must have created the target database already and granted permissions to it for the MySQL Workbench user.
