[c-nsp] Nexus 7K NX-OS Upgrade

[Tim Stevenson]

Hi Antonio,

The difference between the two procedures is that 
"install all" will perform an in-service software 
upgrade, ie, this should be non disruptive to the 
data plane while the sups and all the modules will upgrade to the new version.

Versus just changing the boot strings and 
rebooting, which is clearly disruptive to the 
entire system. In the end, both should result in 
all sups & modules running the new release.

Not sure what issues you ran into with ISSU, 
would at a minimum suggest you check the release 
notes to make sure the starting and target releases are compatible etc.

Hope that helps,
Tim
