If you created a backup of the ESXi host configuration, you can restore the configuration.

To restore a configuration on a host, you must run the vSphere CLI virtual appliance from a remote host. When you restore the configuration, the target host must be in maintenance mode, which means all virtual machines (including the vSphere CLI virtual appliance) must be powered off.

For more information, see the ESXi and vCenter Server Setup Guide.

For more information about the VMware vSphere Command-Line Interface and the vicfg-cfgbackup command, see the vSphere Command-Line Interface Installation and Reference Guide.
