ApsaraDB for Redis allows you to upgrade or downgrade an instance based on your business requirements to optimize resource usage and data management in a cost-effective manner.
You can change the instance configuration at any time. For more information, see Change specifications.
A pay-as-you-go instance is billed based on the specifications that are used when a billing order is generated.
You can change the specifications of a subscription instance before or after the instance expires. Higher specifications are charged more than lower specifications. For example, the price of an 8 GB read/write splitting instance with 5 read replicas is higher than that of a 16 GB cluster instance. If you want to change a 16 GB cluster instance to an 8 GB read/write splitting instance with 5 read replicas, you must upgrade the instance.
|Upgrade||Total fees for instance upgrade = (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)|
|Downgrade||Downgrade refunds = (Daily fees of the instance before downgrade - Daily fee of the instance after downgrade) × (Number of days between the subscription expiration date and the downgrade date)|
If the remaining days before service expiration are less than 365 days, the fees are incurred based on the monthly subscription price. If the remaining days are more than or equal to 365 days, the fees are incurred based on the annual subscription price.
