You can change the specifications of your instance based on your business requirements. The following table describes information about specification changes and billing details.

Billing method Specification changes description Billing description
Subscription
  • During the specification changes, the instance may be disconnected for seconds. We recommend that you change specifications of an instance during off-peak hours. Make sure that your applications can automatically reconnect to the instance after disconnection.
  • After you change specifications, the instance is billed based on the new specifications.
  • You can change the instance specifications at your convenience within the contract period. However, if an unpaid renewal order exists under the same account, specification changes are not allowed.
    • Total fees for upgrading an instance = (Daily fees of the instance after upgrade - Daily fees of the instance before upgrade) × (Number of days between the subscription expiration date and the upgrade date)
    • If the remaining days before service expiration are less than 365 days, the fees are charged based on the monthly subscription price. If the remaining days are greater than or equal to 365 days, the fees are charged based on the annual subscription price.
  • The new specifications that you select during renewal take effect in the new billing cycle. Your instance is billed based on the new specifications and subscription period. For example, if a subscribed instance expires on June 20, 2017 and you renew the instance and upgrade the instance specifications on May 10, 2017, then the instance will be renewed and upgraded on June 20, 2017.
  • If you upgrade or downgrade an instance during the renewal, the instance is billed based on the new specifications and subscription period.
Pay-as-you-go
  • The instance is billed based on the specifications that are used when the system generates a billing order.
