Click Save to file, and then choose a location on your workstation to
8.
temporarily store the .upg upgrade file.
Post the .upg file that you downloaded to a designated area on your network

that is accessible to all your GSS devices.
You are now ready to upgrade the software on a GSS device. See the
Your GSS Devices"
section.
Before upgrading from an earlier version of GSS to v2.0, you should do the
following:
Be aware of these considerations when CNR is installed and enabled:
•
–
The Name Service (NS) forwarding feature does not work on v2.0 if CNR
is enabled. For example, if a DNS rule has been configured to perform
NS forwarding in clause1 on v1.3.3 and you then upgrade to v2.0 with
CNR installed and enabled, all DNS requests will be forwarded directly
to CNR. This action occurs even if there is a matching DNS rule with NS
forwarding configured on the GSS.
–
To obtain support for reverse lookup for the answers configured on the
GSS, you need to explicitly configure the Pointer (PTR) records to do the
same on CNR.
To perform NS forwarding on GSS v2.0 (without CNR) to a name service
–
that is GSS/CNR, you must configure a proper domain name in the
domain name field in the NS type answer configuration. In addition, the
external name server must be authoritative for the domain name if the
name server is GSS/CNR. By default, the NS type answer queries for ".".
To obtain the same expiration level for the records returned by the GSS
–
and the CNR, you need to ensure that the TTL configuration is the same
on both the CNR and GSS.
To have the GSS/CNR device process the NON A records for the
–
authoritative domain, you must configure all the NON A records on the
CNR that were earlier processed by the external name service using NS
forwarding.
