    :MigrateToOtherZone

    Last Updated:Dec 09, 2024

    Migrates a Tair (Redis OSS-compatible) instance across zones within the same region.

    Operation description

    Before you call this operation, you must release the public endpoint (if any) of the instance. For more information, see Migrate an instance across zones.

    Note

    • If the network type of an ApsaraDB for Redis instance is switched from classic network to Virtual Private Cloud (VPC), and the classic network endpoint is retained, you can migrate the instance across zones only after the classic network endpoint is released upon expiration.

    • After the instance is migrated, the endpoint of the instance remains unchanged. However, the virtual IP address (VIP) is changed. We recommend that you use the endpoint instead of the VIP to connect to the instance.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    DBInstanceIdstringYes

    The ID of the ApsaraDB for Redis instance.

    		r-bp1zxszhcgatnx****
    ZoneIdstringYes

    The ID of the destination primary zone. You can call the DescribeZones operation to query zone IDs.

    		cn-hangzhou-g
    VSwitchIdstringNo

    The ID of the vSwitch.

    Note
  • The vSwitch must be deployed in the zone that is specified by the ZoneId parameter.
  • If the network type of the instance is VPC, this parameter is required.
    •
    		vsw-bp1e7clcw529l773d****
    EffectiveTimestringNo

    Specifies the time when the database is switched after data is migrated. Valid values:

    • Immediately: immediately switched after the data is migrated.
    • MaintainTime: switched within the maintenance window.
    • 0: immediately switched after the data is migrated.
    • 1: switched within the maintenance window.
    Note Default value: Immediately.
    		Immediately
    SecondaryZoneIdstringNo

    The ID of the destination secondary zone. You can call the DescribeZones operation to query zone IDs.

    Note You can specify this parameter to deploy the master node and replica node in different zones to implement zone-disaster recovery. This helps withstand data center-level breakdowns.
    		cn-hangzhou-h
