This topic describes how to switch an ApsaraDB RDS for SQL Server instance from pay-as-you-go to subscription.
Prerequisites
- The instance type of your RDS instance is not phased out. For more information, see Primary instance types. If your RDS instance uses a phased-out instance type, you must change the instance type before you switch your RDS instance from pay-as-you-go to subscription. For more information, see Change the specifications of an ApsaraDB RDS for SQL Server instance.
- Your RDS instance uses the pay-as-you-go billing method.
- Your RDS instance is in the Running state.
- Your RDS instance does not have an unpaid subscription order.
Impacts
This operation does not have impacts on the running of your RDS instance.
Precautions
If your RDS instance has an unpaid subscription order, the order becomes invalid when you change the instance type. In this case, you must cancel the order in the Billing Management console. Then, you can change the billing method of your RDS instance again.
