Updates the minor version of an ApsaraDB for Redis instance.

Operation description

The procedure to update the minor version of an instance varies based on types of ApsaraDB for Redis instances. For more information, see Upgrade the minor version.

  • Before you call this operation, you can call the DescribeEngineVersion operation to query the minor version of the current instance.
  • When you switch your workloads over from the original instance to a new instance or from the master node to the replica node in the original instance, you may experience disconnections that last a few seconds. The original instance stays in the read-only state within 60 seconds until all data is synchronized. We recommend that you upgrade the original instance during off-peak hours and make sure that your application is configured to automatically reconnect to the original instance.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
