Deprecated since version 4.0.


Starting in version 4.2, MongoDB removes the clone command. The deprecated db.cloneDatabase(), which wraps the clone command, can only be run against MongoDB 4.0 or earlier versions. For behavior and examples, refer to the 4.0 or earlier version of the manual.

For an alternative in version 4.2+, see Copy/Clone a Database.

Copies a remote database to the current database. The command assumes that the remote database has the same name as the current database.

Parameter Type Description
hostname string The hostname of the database to copy.
