Data Transmission Service:Change the billing method

Last Updated:Dec 01, 2025

You can change the billing method of a data synchronization or change tracking task to pay-as-you-go or subscription based on your business needs. This change does not affect the operation of the DTS instance.

Usage notes

  • In the new console, you can switch between the pay-as-you-go and subscription billing methods. In the previous-version console, you can only change the billing method from pay-as-you-go to subscription. We recommend that you use the new console.

  • The billing method for data migration tasks is pay-as-you-go only. You cannot change it.

  • If you want to convert a regular synchronization instance to a Serverless instance, see Convert a synchronization instance to a Serverless instance.

  • In the new console, the instance ID remains unchanged after you change the billing method. In the previous-version console, the instance ID changes.

  • After you change the billing method of an instance from subscription to pay-as-you-go, the remaining balance is refunded to your original payment method.

  • You cannot change the billing method for a data verification task.

Prerequisites

  • A DTS data synchronization, Serverless, or change tracking instance is created.

  • If you use the previous-version console to change the billing method from pay-as-you-go to subscription, you must prepare a subscription task to be the destination for the change. The task must meet the following requirements:

    • For data synchronization tasks, the Source Instance, Source Region, Destination Instance, Destination Region, and Synchronization Topology must be the same as those of the task being modified.

    • Change tracking task: The Source Region must be the same as those of the existing change tracking task.

Description

Subscription

  • Also called upfront. You pay for the instance when you create it.

  • This method is suitable for long-term use and is more cost-effective than pay-as-you-go. You receive larger discounts for longer subscription durations.

Pay-as-you-go

  • Also called post-paid. You are billed hourly. The fee is based on the instance type and is deducted from your Alibaba Cloud account.

  • This method is suitable for short-term use. You can release the instance immediately after use to save costs.

Serverless

A dynamic billing method that adjusts resources at a minute-level based on the instance workload. You are billed hourly for your actual usage. This method can significantly lower your costs.
