  2. Specify the database attributes:

    • Authentication source is the MongoDB database name associated with the username and password below.

    • Username for connection to the MongoDB database.

    • Password for the database user.

    • Database name is the name of the database to which you want to transfer your data.


      If you don't specify a database name, the collections will be created in databases with the same names as on the source.

      If the field isn't empty, all data will be placed in the specified database.

    • Cleanup policy. This policy allows you to select a way to clean up data in the target database when you activate, reactivate or reload the transfer:

      • Disabled: Do not clean. Select this option if you only perform replication without copying data.

      • Drop: Fully delete the collections included in the transfer (default). Use this option to always transfer the latest version of the schema to the target database from the source.

      • Truncate: Execute the remove() command for a target collection each time you run a transfer.

    The completed from should look as follows:
