Procedure Go to the vSAN cluster. Select the Configure tab, verify that the vSAN is listed. NOTE: You can also go to the ESXi host, and select Summary > Configuration. Verify that the latest version of the ESXi host is in use. Under vSAN, click Disk Management. All disks should be running version 11.0. Parent topic Upgrade to VMware vSphere 7.0Some VxBlock System components are optional or specific to environments. If you do not have a specific component, skip that component. When the component is in a cluster configuration, upgrade the subordinate component before you upgrade the primary component.
