You can remove any Broker VM that is no longer needed.
Cortex XDR allows you to remove a Broker VM directly from both the Brokers tab and Clusters tab of the Broker VMs page.
When you remove a Broker VM node that is added to high availability (HA) cluster, the Broker VM is also removed from the cluster on the tenant.
Select→ → → .
In either the Brokers tab or Clusters tab, locate your Broker VM, right-click, and select Remove Broker.
