Installation guide

The host is upgraded to ESXi 4.0. If the upgrade fails, restart vSphere Host Update Utility before you retry the
upgrade.
vSphere Host Update Utility might appear to stop working. If this happens, wait several minutes to see if the
utility starts working again. VMware recommends that you do not cancel the upgrade at any point during the
upgrade process. The host might appear to successfully boot into ESXi 4.0. If this happens, continue to wait
until the message Upgrade Succeeded appears before you close the utility.
