You can run the upgrade script by using the vSphere console for the virtual machine or by using an SSH
console session. If you use the vSphere console, you avoid intermittent network connectivity problems
that can break the execution of the script.
If you stop the script while it is upgrading a component, the script stops when it finishes upgrading the
component. If other components on the node still must be upgraded, you can run the script again.
When the upgrade finishes, you can review the upgrade result by opening the upgrade log file
at /opt/vmware/var/log/vami/upgrade-iaas.log.
