Updating NetWorker by using Client Push 51
Updating from a previous release
By default, the Clone Storage Node attribute for each storage node resource does not
contain any values. If required, after updating the NetWorker server software, modify the
Clone Storage Node attribute for each storage node. The section
Directing clones to a
special storage node
in the NetWorker 8.1 Administration Guide provides more
information.
Optional, converting VCB client backups to VADP
The NetWorker 7.6 SP2 software and later supports a backup and recovery of VMware
clients that uses the vStorage APIs for Data Protection (VADP) program. The NetWorker 7.6
SP2 and earlier software uses the VMware Consolidated Backups (VCB) program to protect
VMware clients.
If you update the NetWorker server and the VM Proxy server from a version before
NetWorker 7.6 SP2, use the nsrvadpserv_tool tool to convert virtual clients from VCB to
VADP backups. The
NetWorker VMware Integration Guide provides more information.
Confirming the update of all storage nodes
The NetWorker 8.1 server does not support a NetWorker 7.6.x and earlier storage node.
Ensure that each NetWorker storage node in the datazone runs the NetWorker 8.1
software. “Determining the NetWorker version on the storage nodes” on page 40
describes how to determine the NetWorker version running on all storage nodes in the
datazone.
Authorizing the NetWorker server
The NetWorker software adds a required update enabler code to the NetWorker server
configuration. You cannot delete this enabler code. The update enabler code expires 45
days after the NetWorker server update, unless you use capacity-based licensing.
Contact EMC Licensing within 45 days of upgrading the NetWorker server to permanently
authorize the update enabler. The
NetWorker Licensing Guide describes how to authorize
an update enabler and how to use the capacity-based license model.

If the update enabler expires or you do not apply the authorization code, the NetWorker
software will not function at the new release level.
Updating NetWorker by using Client Push
Use the software distribution feature, Client Push, to update the NetWorker and module
software on NetWorker hosts in the datazone from the NetWorker server. You need not log
in to each host and manually uninstall the old NetWorker software version and install the
new NetWorker software version.
The following sections describe how to use client push:
◆ “Client Push requirements” on page 52
◆ “Preparing the Media Kit Location” on page 53
◆ “Preparing the software repository” on page 54
