Data Transmission Service:Release DTS instances

Last Updated:Jun 16, 2026

You can manually release a pay-as-you-go DTS instance after its tasks are complete and you no longer need the instance configurations. Releasing unused instances avoids extra costs.

Usage notes

  • The DTS instance must use the pay-as-you-go billing method.

    Note

    You cannot manually release a subscription instance. An unrenewed subscription instance is automatically released seven days after it expires.

  • After a DTS instance is released, all data is deleted and cannot be recovered. Proceed with caution.

  • A synchronization or migration instance with a verification task appears in both its task list (Data Synchronization Tasks or Data Migration Tasks) and the Verification Task list. Exercise caution when performing operations.

  • DTS instances purchased during promotional events cannot be released.

Release one or multiple pay-as-you-go instances

  1. Log on to the DTS console.
  2. In the navigation pane on the left, click Data Migration, Data Synchronization, Data Verification, or Change Tracking, based on the instance type.

  3. In the top navigation bar, select the region in which your instances reside.

  4. Release one or multiple DTS instances.

    • Release a single DTS instance

      In the Actions column of the instance that you want to release, choose More > Delete Task.

    • Release multiple DTS instances at a time

      Select multiple instances that you want to release and click Delete Task in the lower part of the page.

  5. In the confirmation dialog box, click OK.

What to do next

After a DTS task is complete or a DTS instance is released, we recommend that you remove the CIDR blocks of DTS servers from the security settings of the source and destination database instances to prevent continued DTS access. For more information, see the CIDR blocks of DTS servers section of the Add the CIDR blocks of DTS servers topic.

  • Remove the IP whitelist group whose name contains dts from the IP address whitelist of each Alibaba Cloud database instance.

  • Remove the security group whose name contains DTS from the security rules of your ECS instance.

  • You must remove the CIDR blocks of DTS servers from the security settings of self-managed databases or databases hosted on third-party cloud platforms.
