Parameter | Description |
Task Name | The task name that DTS automatically generates. We recommend that you specify a descriptive name that makes it easy to identify the task. You do not need to specify a unique task name. |
Instance Type | The access method of the source database. In this example, User-Created Database in ECS Instance is selected. Note If you select other instance types, you must deploy the network environment for the self-managed database. For more information, see Preparation overview. |
Instance Region | The region of the Elastic Compute Service (ECS) instance on which the source TiDB database is deployed. |
Database Type | Select TiDB. |

Database Password | The password of the database account. Important After you specify the information about the source database, you can click Test Connectivity next to Database Password to check whether the information is valid. If the information is valid, the Passed message appears. If the Failed message appears, click Check next to Failed. Then, modify the information based on the check results. |
Incremental migration or not | Specifies whether to perform incremental data migration. In this example, Yes is selected. For more information about how to perform only full data migration, see Migrate full data from a self-managed TiDB database to an ApsaraDB RDS for MySQL instance. |

If the Kafka cluster is connected over other methods, you must deploy the network environment for the Kafka cluster. For more information, see Preparation overview. Note You cannot select Message Queue for Apache Kafka for the Kafka Cluster Type parameter.
