Upgrade host specifications
After you create an ApsaraDB for MyBase host, you can upgrade its specifications if its current specifications no longer meet your business requirements. This topic describes how to upgrade host specifications.
Prerequisites
You have created an ApsaraDB for MyBase cluster for MySQL High-availability Edition.
You have created a host that uses a local SSD or an ESSD. For more information, see Add a MySQL host.
You have confirmed that the current host specifications can be upgraded. For more information, see Supported upgrade specifications.
Usage notes
-
Host specifications can be upgraded, but not downgraded.
-
The Upgrade Specifications option is dimmed and host specifications cannot be upgraded in the following scenarios:
-
An instance is being created on the host.
-
An instance that runs on the host is being migrated.
-
The host is locked due to expiration.
-
-
Host specifications can be upgraded only within the same instance family. For more information about host instance types, see Dedicated host type details.
-
When you upgrade host specifications, you must increase both the CPU cores and memory.
-
The interval at which you upgrade the specifications of one host is at least 10 minutes.
-
When you upgrade the specifications of a host, the host and its running instances restart.
Note-
When a host restarts, a primary/secondary instance switchover occurs on the host. This may cause one or two transient connections.
-
The amount of time it takes to restart a host varies based on the duration of the primary/secondary instance switchover.

Billing rules
The following formulas are 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.
