If a data migration or data synchronization task cannot meet your business requirements, you can upgrade the instance class of the task in the Data Transmission Service (DTS) console.
- The DTS task is in the Running, Paused, or Failed state.
- The task is a data migration or data synchronization task. You do not need to configure instance class for change tracking tasks.
- If the billing method is subscription,
Task configuration fee = (Daily fee of the task after upgrade - Daily fee of the task before upgrade) × (Subscription expiration date - Upgrade date)Note The daily fee of a task after upgrade depends on the number of remaining days from the upgrade date to the expiration date.
- If the number of remaining days is less than 300 days, the fee of the task after upgrade equals the fee offered by monthly subscription.
- If the number of remaining days is greater than or equal to 300 days, the fee of the task after upgrade equals the fee offered by annual subscription.
- If the billing method is pay-as-you-go,
The task configuration fee is calculated based on the new instance class of the task. The billing rules remain unchanged. A bill is generated on an hourly basis.
- Log on to the DTS console.
- In the left-side navigation pane, click Data Migration or Data Synchronization.
- Find the data migration or data synchronization task and choose .
- Select a new instance class. Then, read and select Data Transmission Service (Pay-as-you-go) Service Terms. Note

- If you need to change the synchronization topology of a data synchronization task, make sure that all the relevant requirements are met. For more information, see Upgrade synchronization topology from one-way to two-way.
- Click Pay and follow the instructions to complete the payment.
