Instance ID | The ID of the source PolarDB for PostgreSQL cluster. |
Database Name | The name of the database that contains the objects to be synchronized in the source PolarDB for PostgreSQL cluster. |
Database Account | The account of the source PolarDB for PostgreSQL database. For more information about the permissions that are required for the database account, see the "Permissions required for database accounts" section of this topic. |
Database Password | The password that is used to access the database. |
Destination Database | Select Existing Connection | The database that you want to use. You can choose whether to use an existing database based on your business requirements.

Note If you set Encryption to SSL-encrypted for a self-managed PostgreSQL database, you must upload CA Certificate. If you want to use the client certificate, you must upload Client Certificate and Private Key of Client Certificate and specify Private Key Password of Client Certificate. For information about how to configure SSL encryption for an ApsaraDB RDS for PostgreSQL instance, see SSL encryption.
