VMware vSphere® 5.0 Upgrade

Best Practices

Reconnecting the Host in vCenter

Following the host upgrade and reboot, reconnect the host in vCenter. From the Hosts and Clusters view, right-

click the host and choose Connect. After the host has been reconnected, verify the conﬁguration.

After the conﬁguration has been veriﬁed, take the host out of maintenance mode. From the Hosts and Clusters

view, right-click the upgraded host and select Exit Maintenance Mode.

Proceed to upgrade the remaining hosts in the cluster.

Rolling Back from a Failed ESXi Installer Upgrade

During the upgrade, the older ESX/ESXi ﬁles on the boot disk are overwritten. Therefore, there is no rollback

capability. To restore a host to its pre-upgraded state, you must ﬁrst reinstall the ESX/ESXi 4.x software and

then restore the host conﬁguration.
