If the current billing method of your PolarDB cluster does not meet your business requirements, you can change the billing method.
Usage notes
A Serverless cluster uses the pay-as-you-go billing, which cannot be changed.
NoteIf you want to migrate a non-serverless cluster (subscription or pay-as-you-go cluster) to a serverless cluster, you need to use Data Transmission Service (DTS). For more information, see How do I migrate a non-serverless cluster (subscription or pay-as-you-go cluster) to a serverless cluster?.
Make sure that your account balance is sufficient to prevent downtime caused by overdue payments after you change the billing methods of compute nodes or storage to pay-as-you-go.
Impact
Your business operations are not affected when you change the billing method of compute nodes and storage.
Refunding
After you change the billing method from subscription to pay-as-you-go, the remaining subscription payment is refunded to your original payment account. Take note that only the actual paid amount is refunded to the original payment channel. Vouchers or coupons that are used are not refunded. For information about how the refund is calculated when the billing method is changed from subscription to pay-as-you-go, see Request a refund after the change of the billing method from subscription to pay-as-you-go.
