You import ESXi images in ISO format to the vSphere Lifecycle Manager local depot, so that you can create upgrade baselines, which you use for host upgrade operations.
You can use ESXi .iso images to upgrade ESXi 6.5.x hosts and ESXi 6.7.x hosts to ESXi 7.0.
With vSphere Lifecycle Manager 7.0, you cannot perform ESXi upgrades to version 6.7 or 6.5.ISO images can only be used with vSphere Lifecycle Manager baselines. You cannot use an ISO image to upgrade the hosts in a cluster that uses a single image.
To upgrade hosts, use the ESXi installer image distributed by VMware with the name format VMware-VMvisor-Installer-7.0.0-build_number.x86_64.iso or a custom image created by using vSphere ESXi Image Builder. You can also use ISO images created and distributed by OEMs.
