Table Of Contents
The upgrade of a distributed switch causes the hosts and virtual machines attached to the switch to
experience a brief downtime. For more information, see KB 52621.
Note To be able to restore the connectivity of the virtual machines and VMkernel adapters if the upgrade
fails, back up the configuration of the distributed switch.
If the upgrade is not successful, to recreate the switch with its port groups and connected hosts, you can
import the switch configuration file. See Export vSphere Distributed Switch Configurations and Import a
vSphere Distributed Switch Configuration.
