Is ist possible to update virtual NAC gateways and Analyticsappliance without an internetaccess?

[andreas]

I ́ve upgrade the Management to 8.0.2.42, and now i ́ll try to update the NAC and Analytics Appliances to this Version. Actually the works with 7.1.1.9. During the updateproccedure the need internetaccess, but we only have internet with a proxyserver.

Is there any way to update without direct connection to internet ?

Thank you, for your answers.
Is it possible, to configure proxysettings in Analytics and/or NAC aplliances.
If not, then i had to reinstall.

consider to not upgrade engines but deploy new OVA (if on vmware) and enforce settings from EMC. The config is in EMC, there is not much in engines...

"there is not much in engines..."

Not much is correct but there is no list/document that explains what is saved in EMC and what is stored directly in the NAC engine.
I've requested such document more then once because "not much" isn't nothing and could have a big impact.

From the release notes page#15
http://documentation.extremenetworks.com/release_notes/NetSight/9035078-02_ExtremeManagementCenter_8...

- When upgrading the Management Center server, Application Analytics engine,
or Access Control engine to version 8.0, ensure the DNS server IP
address is correctly configured.
Additionally, upgrading requires an internet connection.
If no internet connection is available, see Upgrading a Hardware Engine.

The problem is that I can't open the linked document.
