1. API Description

Domain name for API request: cdb.tencentcloudapi.com.

This API (UpgradeDBInstance) is used to upgrade database instances. Master instances, disaster recovery instances and read-only instances can be upgraded via this API.

A maximum of 20 requests can be initiated per second for this API.

Note: This API supports Finance regions. Since Finance regions and non-Finance regions are isolated and not interconnected. If the common parameter Region is a Finance region (such as ap-shanghai-fsi), you need to specify a domain name containing the Finance region that should be identical to the value of Region field, for example: cdb.ap-shanghai-fsi.tencentcloudapi.com.
