After you create a host in an ApsaraDB MyBase dedicated cluster, you can change the host specifications to meet your business requirements. This topic describes how to upgrade host specifications.
Prerequisites
- A host is created in an ApsaraDB MyBase for PostgreSQL dedicated cluster. For more information, see Create a host in an ApsaraDB MyBase for PostgreSQL dedicated cluster.
- The host specifications can be upgraded. For more information, see the Host specifications that can be upgraded of this topic.

Billing
The following formula is used to calculate the fees for upgrading host specifications:
Upgrade fees = Total fees of the new specifications for the remaining subscription period - Total fees of the original specifications for the remaining subscription period. Total fees of the new specifications for the remaining subscription period = Monthly fees of the new specifications/30/24 × Unused hours. Total fees of the original specifications for the remaining subscription period = Monthly fees of the original specifications/30/24 × Unused hours.
For example, assume that the monthly fees of the new specifications are USD 14,400, the monthly fees of the original specifications are USD 7,200, and the host is to expire after 50 days. In this case, the following formula is used to calculate the upgrade fees: (14400/30/24 × 50 × 24) - (7200/30/24 × 50 × 24) = 12000.
