I have tried to upgrade image version from 2.0(2) to 3.0(2) for my GSS4492R.
according the gss upgrade doc for version 3.0 I did:
Proceed with install (the device will reboot)? (y/n): y
Performing software install. This will take a few minutes.
If you close this session, the installation will still complete.
% Upgrade failed: The install script from the upgrade file failed.
% The GSS is not running.
It seems can not upgrade for me. Could I get some advice about the problem?
Any comment will be appreciated'
Thanks in advance
You can't upgrade from 2.0(2) to 3.0(2) directly, as there is an intermediate upgrade required.
