By using ESXCLI, you can upgrade an ESXi 6.5 host or ESXi 6.7 host to version 7.0 and update or patch ESXi 6.5, ESXi 6.7, and ESXi 7.0 hosts.
vSphere 7.0 introduces components, base images, and add-ons as new software deliverables that you can use to update or patch ESXi 7.0 hosts. For information about managing components, base images, and add-ons on ESXi, see ESXCLI Concepts and Examples
To use ESXCLI commands, you must install Standalone ESXCLI. For more information about installing and using ESXCLI, see the following documents.
If you press Ctrl+C while an esxcli command is running, the command-line interface exits to a new prompt without displaying a message. However, the command continues to run to completion.
For ESXi hosts deployed with vSphere Auto Deploy, the tools VIB must be part of the base booting image used for the initial Auto Deploy installation. The tools VIB cannot be added separately later.
