    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: UpgradeDBInstance.
    Version Yes String Common Params. The value used for this API: 2017-03-20.
    Region No String Common Params. This parameter is not required for this API.
    InstanceId Yes String Instance ID in the format of cdb-c1nl9rpv or cdbro-c1nl9rpv. It is the same as the instance ID displayed on the TencentDB Console page. You can use the DescribeDBInstances API to query the ID, whose value is the InstanceId value in output parameters.
    Memory Yes Integer Memory size in MB after upgrade. To ensure that the Memory value to be passed in is valid, please use the DescribeDBZoneConfig API to query the specifications of the memory that can be upgraded to.
    Volume Yes Integer Disk size in GB after upgrade. To ensure that the Volume value to be passed in is valid, please use the DescribeDBZoneConfig API to query the specifications of the disk that can be upgraded to.
    ProtectMode No Integer Data replication mode. Valid values: 0 (async), 1 (semi-sync), 2 (strong sync). This parameter can be specified when upgrading primary instances and is meaningless for read-only or disaster recovery instances.
    DeployMode No Integer Deployment mode. Valid values: 0 (single-AZ), 1 (multi-AZ). Default value: 0. This parameter can be specified when upgrading primary instances and is meaningless for read-only or disaster recovery instances.
    SlaveZone No String AZ information of secondary database 1, which is the Zone value of the instance by default. This parameter can be specified when upgrading primary instances in multi-AZ mode and is meaningless for read-only or disaster recovery instances. You can use the DescribeDBZoneConfig API to query the supported AZs.
    EngineVersion No String Version of primary instance database engine. Valid values: 5.5, 5.6, 5.7.
    WaitSwitch No Integer Switch mode for accessing the new instance. Valid values: 0 (switch immediately), 1 (switch within a time window). Default value: 0. If the value is 1, the switch process will be performed within a time window. Or, you can call the SwitchForUpgrade API to trigger the process.
    BackupZone No String AZ information of secondary database 2, which is empty by default. This parameter can be specified when upgrading primary instances and is meaningless for read-only or disaster recovery instances.
    InstanceRole No String Instance type. Valid values: master (primary instance), dr (disaster recovery instance), ro (read-only instance). Default value: master.
    DeviceType No String The resource isolation type after the instance is upgraded. Valid values: UNIVERSAL (general instance), EXCLUSIVE (dedicated instance), BASIC (basic instance). If this parameter is left empty, the resource isolation type will be the same as the original one.
    Cpu No Integer The number of CPU cores after the instance is upgraded. If this parameter is left empty, the minimum value will be automatically filled based on the value specified by Memory.
    FastUpgrade No Integer QuickChange options. Valid values: 0 (common upgrade), 1 (QuickChange), 2 (QuickChange first). After QuickChange is enabled, the required resources will be checked. QuickChange will be performed only when the required resources support the feature; otherwise, an error message will be returned.
    MaxDelayTime No Integer Delay threshold. Value range: 1-10. Default value: 10.
    CrossCluster No Integer Whether to migrate the source node across AZs. Valid values: 0 (no), 1(yes). Default value: 0. If it is 1, you can modify the source node AZ.
    ZoneId No String New AZ of the source node. This field is only valid when CrossCluster is 1. Only migration across AZs in the same region is supported.
    RoTransType No String Processing logic of the intra-AZ read-only instance for cross-cluster migration. Valid values: together (intra-AZ read-only instances will be migrated to the target AZ with the source instance by default.), severally (intra-AZ read-only instances will maintain the original deployment mode and will not be migrated to the target AZ.).

    3. Output Parameters
