This topic describes how to switch the billing method of an Apsara PolarDB cluster from pay-as-you-go to subscription based on your business requirements.


  • You cluster runs in the Running state.
  • No pending orders for switching from pay-as-you-go to subscription. If pending orders exist, you must pay for or cancel them on the Orders page.

Background information

After you switch the billing method from pay-as-you-go to subscription, the cluster still runs as expected.
Note Before you switch the billing method, you must first upgrade the specification. If a cluster uses a specification that is no longer available, you cannot switch the billing method to subscription. For more information, see Change specifications.

  2. In the upper-left corner of the console, select the region where the target cluster is deployed.
  3. In the left-side navigation pane, click Clusters and find the target cluster on the Clusters page. In the Actions column of the cluster, choose ... > Switch to Subscription.Switch to subscription
  4. Specify Purchase Plan, read and accept the Apsara PolarDB (Subscription) Agreement of Service, and then click Pay to complete the payment.
    • The new billing method takes effect after you complete the payment.
    • If the order is unpaid or the payment fails, an unfinished order appears on the Orders page. You cannot purchase a new cluster or switch the billing method to subscription before you complete the payment. You must complete payment or cancel the order before placing a new one.
