Scenarios

If the current cluster specifications do not meet your business requirements, you can upgrade your cluster and storage specifications in the console.
Note:
Currently, only pro clusters support upgrading cluster specifications, while virtual clusters do not. The upgrade process does not affect business operations theoretically. However, during the upgrade, as the server rebalances the topic traffic, the client may experience disconnections and reconnections.

Operation Steps

2. In the left sidebar, choose Pulsar > Cluster. On the Cluster list page, find the target cluster and choose More > Upgrade in the operation column.
3. After selecting the target cluster specifications, click Confirm the Adjustment.
