If an in-place upgrade fails for an ESXi 7.0 host, except when you see a PSOD, vMotion the VMs out of the host and then reboot the host.
- Log in to vCenter Server and place the host in maintenance mode.
- For an ESXi 7.0 host, use the following command to clear the upgrade status flag on the host:
nsxcli -c set host-switch upgrade-status false
- vMotion the VM's out of the host.
- Reboot the host and resume the upgrade process.
