You can upgrade the minor version of your ApsaraDB for Cassandra cluster directly from the console.
Procedure
Important The upgrade process updates each node in the cluster sequentially. Some upgrades require a node restart to take effect, which can impact cluster operations:
- For clusters with a high availability configuration, nodes are upgraded sequentially. This process does not interrupt your service, and your cluster remains online throughout the upgrade.
- For clusters without a high availability configuration, if an upgrade requires a node to restart, that node becomes temporarily unavailable. Any application that attempts to access the node during the restart will fail.
- Log on to the ApsaraDB for Cassandra console and click the name of the target cluster to open its details page.
- On the Cluster Details page, click Upgrade Minor Version.
- In the dialog box that appears, click OK to start the upgrade.
