This topic describes how to release pay-as-you-go instances in the Data Transmission Service (DTS) console.

Usage notes

  • The billing method of your DTS instances must be pay-as-you-go.
    Note You cannot manually release a subscription instance. If you do not renew a subscription instance after it expires, the instance will be automatically released seven days later.
  • If a DTS instance is released, it cannot be retrieved.

Release pay-as-you-go instances

  1. Log on to the DTS console.
  2. In the left-side navigation pane, click Data Migration, Data Synchronization, or Change Tracking.
  3. In the top navigation bar, select the region in which your instances reside.
  4. Release one or more DTS instances.
    • Release a DTS instance

      Find the instance that you want to release, click the More icon in the Actions column, and then select 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 message that appears, click OK.

What to do next

After a DTS task is complete or a DTS instance is released, we recommend that you manually remove the CIDR blocks of DTS servers from the security settings of the source and destination database instances. This way, DTS can no longer access the source and destination databases. For more information, see the "CIDR blocks of DTS servers" section of the Add the CIDR blocks of DTS servers to the security settings of on-premises databases topic.
  • Among the IP address whitelists of Alibaba Cloud database instances, delete the IP address whitelists whose names contain dts.
  • For the security group rules of Elastic Compute Service (ECS) instances, delete the security groups whose names contain DTS.
  • In the security settings of self-managed databases or databases hosted on third-party cloud services, remove the CIDR blocks of DTS servers.
