Upgrade Workload Clusters
After completing the upgrade of the global cluster, you can proceed to upgrade the workload clusters. The workload cluster upgrade process is similar to that of the global cluster but requires attention to the following considerations:
- If your platform uses the global disaster recovery (DR) solution, you must complete the upgrade of both the primary and standby global clusters before upgrading any workload clusters.
- All PostgreSQL instances will be automatically restarted during the upgrade.
- For MySQL-PXC, MySQL-MGR, Redis, Kafka, and RabbitMQ instances configured with an automatic update strategy, the upgrade process includes a restart, which may lead to temporary service disruption.
- A maximum of 20 workload clusters can be upgraded concurrently.

WARNING
- If you plan to upgrade the Operator and Cluster Plugin while upgrading the workload cluster, please push the corresponding packages to the corresponding cluster's registry in advance. For bulk upload instructions, see Push all packages at once.
Upgrade the workload cluster
- Log into the Web Console and switch to the Administrator view.
- Navigate to Clusters > Clusters.
- Select the workload cluster you want to upgrade and open its detail page.
- Go to the Functional Components tab.
- Click the Upgrade button.
If the upgrade program detects any custom configuration overrides, you will be prompted to confirm these settings. If you are unsure whether these overridden configurations may impact the upgrade, please contact technical support for assistance.
Once confirmed, a component upgrade dialog will appear. Review the available updates and proceed with the upgrade.
