    Data Transmission Service:Configure a DTS migration or synchronization task

    Last Updated:Sep 08, 2025

    You can configure a data migration or synchronization task.

    • You can preconfigure the task in the console and then preview the corresponding OpenAPI parameters to help you specify the request parameters. For more information, see Preview OpenAPI request parameters.
    • Tasks on a dedicated cluster support only the configure-first, purchase-later billing method. Cross-region tasks are not supported.

    Debug

    You can run this operation in OpenAPI Explorer to simplify the process of calculating signatures. After a successful call, OpenAPI Explorer automatically generates sample SDK code.
