1. API Description

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

This API is used to upgrade or downgrade a TencentDB instance, which can be a primary instance, disaster recovery instance, or read-only instance.

A maximum of 30 requests can be initiated per second for this API.

We recommend you to use API Explorer

Try it

API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

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

Parameter Name	Type	Description
DealIds	Array of String	Order ID.
AsyncRequestId	String	Async task request ID, which can be used to query the execution result of an async task.
RequestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
