Network Communication Mode
Currently, if you need to migrate data from an on-premises MySQL instance to an eSurfing Cloud RDS MySQL instance, you must establish an Internet connection between the instances. This type of connection requires that the database instances and your eSurfing Cloud Data Transmission Service (DTS) instance have public IP addresses.
