You can change the configuration of your instance based on business requirements.The following table lists information about configuration change and billing.
||Configuration change description
- You can only upgrade the instance configuration during the contract period.
- You can choose to upgrade or downgrade the instance configuration when you renew the instance upon expiration.
- You can change the instance configuration in real time within the contract period. However, configuration changes are not allowed when the same account has an unpaid renewal order.
- Upgrade costs = (Daily price of the instance after upgrade – Daily price of the instance before upgrade) × Number of days from the upgrade date to the expiration date
- If the number of days from the upgrade date to the expiration date is less than 365, the daily price of the instance after upgrade is equal to the monthly price. If the number of days is equal to or more than 365, the daily price of the instance after upgrade is equal to the annual price.
- The configuration change you select upon renewal within the contract period takes effect during the new billing cycle, and your instance is billed based on the new configuration and length of service time. For example, if a subscribed instance expires on June 26, 2017 and you renew the instance and upgrade the instance configuration on May 10, 2017, then the instance gets renewed and upgraded on June 26, 2017.
- If you upgrade or downgrade the instance configuration when you renew the instance upon expiration, the instance is billed based on the new configuration and subscription period.
||The instance configuration can be upded or downgraded at any time.
- Billing is based on the instance configuration used when a billing order is generated.
