You can change the billing method of a PolarDB cluster from pay-as-you-go to subscription based on your business requirements.
- Your cluster is in the Running state.
- Your cluster does not have pending orders to change the billing method from pay-as-you-go to subscription. If pending orders exist, you must pay for or cancel them on the Orders page.
- If a cluster uses specifications that are no longer available such as dedicated specifications of 2 cores and 4 GB memory, you cannot change the billing method to subscription. In this case, you must change the cluster specifications before you change the billing method to subscription. For more information, see Manually upgrade or downgrade a PolarDB cluster.
If a subscription cluster uses the storage billing method of subscription, you cannot change it to a pay-as-you-go cluster. However, if a subscription cluster uses the storage billing method of pay-as-you-go, you can change it to a pay-as-you-go cluster.
