N7K ISSU “a long time ago” has evolved drastically.
I vaguely remember that 5.0, 5.1, and 5.2 code each had a scheduler re-write
because things would get bungled up under load. I’m sure some of the TMEs on
this list can comment.
I myself had a few issues moving from 5.1 to 5.2 — causing severa
Actually ISSU is not that stable, I tried it a couple of times "long time ago"
with no luck so I stopped using it at all.

We were required to use long LACP timers for one upgrade. The show impact
command will tell all, in this regard.
As Mike mentioned, if an stp change occurs it will rollback the ISSU.

Make sure use short lacp timeout, no spanning-tree change during the upgrade

I’ll be honest I was pretty confident after reading the config guide on the

The config guide does say ‘one command does it all’ which sounded great! I

I would even go so far as to:
load system/kickstart files
isolate the box (shutdown all ports)
power-cycle the box, let it boot into the new code
perform EPLD updates on all cards

Definitely not a stupid question. While the double ISSU would work we
generally would not do it for big jumps like that.
The problem is that the whole procedure tended to be buggy so we are too
