You can change the billing method of a cluster from pay-as-you-go to subscription based on your needs. Changing billing methods will not impact the performance of your cluster.
Note If a cluster uses a specification that is no longer available, you cannot change the billing method of the cluster to subscription. In this case, you must change the cluster specifications before changing the billing method.


You cannot change the billing method of a cluster from subscription to pay-as-you-go. Consider your resource requirements before switching the billing method to subscription to avoid resource wastage.


  • The cluster must be in the Running state.
  • There are no pending orders for changing the billing method from pay-as-you-go to subscription. If there are any pending orders, you must complete payment for or discard them on the Orders page.


  1. Log on to the ApsaraDB for PolarDB console.
  2. Select the region where the cluster resides.

    • The new billing method takes effect after you complete the payment.
