Updating VMware ESXi Host from the Command Line (ESXCLI)

This article describes how to manually install updates on a VMware ESXi host from the command line using the esxcli tool. You can only install security patches, perform in-release upgrades, or upgrade between ESXi versions (for example, you can upgrade from VMware ESXi 6.7 to 7.0 or 8.0).

A manual ESXi upgrade from the esxcli console is typically used to update a standalone ESXi host (or free VMware vSphere Hypervisor), a small installation, or a test environment. VMware Update Manager/VMware Lifecycle Manager is the preferred way to update large VMware vSphere vCenter (VCSA-based) infrastructure.
