You can specify this parameter only when the original instance runs RDS High-availability Edition. You can select a zone that belongs to the region where the original instance resides. You can call the DescribeRegions operation to query zone IDs.
  • engine - (Optional, Computed, ForceNew) Database type. Value options: MySQL, SQLServer, PostgreSQL.
  • parameters - (Optional, Computed) Set of parameters needs to be set after DB instance was launched. Available parameters can refer to the latest docs View database parameter templates. See parameters below.
  • force_restart - (Optional) Set it to true to make some parameter efficient when modifying them. Default to false.
  • switch_time_mode - (Optional) The time at which ApsaraDB RDS switches your workloads over to the new instance. This parameter is used together with the SwitchOver parameter and takes effect only when you set the SwitchOver parameter to true. Valid values:
    • Immediate: After data is migrated to the new instance, ApsaraDB RDS immediately switches your workloads over to the new instance.
    • MaintainTime: After data is migrated to the new instance, ApsaraDB RDS switches your workloads over to the new instance during the maintenance window that you specify. You can call the ModifyDBInstanceMaintainTime operation to change the maintenance window of an instance.
  • switch_over - (Required) Specifies whether ApsaraDB RDS automatically switches your workloads over to the new instance after data is migrated to the new instance. Valid values:
    • true: ApsaraDB RDS automatically switches workloads over to the new instance. If you set this parameter to true, you must take note of the following information:
      • After the switchover is complete, you cannot roll your workloads back to the original instance. Proceed with caution.
      • During the switchover, the original instance processes only read requests. You must perform the switchover during off-peak hours.
      • If read-only instances are attached to the original instance, you can set this parameter only to false. In this case, the read-only instances that are attached to the original instance cannot be cloned. After the upgrade is complete, you must create read-only instances for the new instance.
    • false: ApsaraDB RDS does not automatically switch your workloads over to the new instance. Before you perform an upgrade, we recommend that you set this parameter to false to test whether the new major engine version is compatible with your workloads. If you set this parameter to false, you must take note of the following information:
  • collect_stat_mode - (Required) The time at which ApsaraDB RDS collects the statistics of the new instance.
    • Before: ApsaraDB RDS collects the statistics of the new instance before the switchover to ensure service stability. If the original instance contains a large amount of data, the upgrade may require a long period of time.
    • After: ApsaraDB RDS collects the statistics of the new instance after the switchover to accelerate the upgrade. If you access tables for which no statistics are generated, the query plans that you specify may be inaccurately executed. In addition, your database service may be unavailable during peak hours.

-> NOTE If you set the SwitchOver parameter to false, the value Before specifies that ApsaraDB RDS collects the statistics of the new instance before the new instance starts to process read and write requests, and the value After specifies that ApsaraDB RDS collects the statistics of the new instance after the new instance starts to process read and write requests.

  • target_major_version - (Required, ForceNew) The major engine version of the new instance. The value of this parameter must be the major engine version on which an upgrade check is performed.

-> NOTE You can call the UpgradeDBInstanceMajorVersionPrecheck operation to perform an upgrade check on a major engine version.

  • tcp_connection_type - (Optional, Available in 1.171.0+) The availability check method of the instance. Valid values:
    • SHORT: Alibaba Cloud uses short-lived connections to check the availability of the instance.
    • LONG: Alibaba Cloud uses persistent connections to check the availability of the instance.

This parameter is used to identify each AD domain. When you add an AD domain, the value of the PriorityId parameter of the new AD domain cannot be the same as the value of the PriorityId parameter for any existing AD domain. When you modify or delete an AD domain, you must also modify or delete the value of the PriorityId parameter for this AD domain.
