You can stage patches and extensions before remediation to ensure that the patches and extensions are downloaded to the host. Staging patches and extensions is an optional step that can reduce the time during which hosts are in maintenance mode.

Staging patches and extensions to hosts that are running ESX/ESXi 4.0 or later lets you download the patches and extensions from the Update Manager server to the ESX/ESXi hosts without applying the patches or extensions immediately. Staging patches and extensions speeds up the remediation process because the patches and extensions are already available locally on the hosts.

Important:

Update Manager does not stage patches to PXE booted ESXi 4.x hosts. Update Manager can stage patches to PXE booted ESXi 5.x hosts.

For more information about staging patches, see Stage Patches and Extensions to ESX/ESXi Hosts.
