Hi Antonio,
In general, doing a traditional upgrade (changing boot variables) will
not update the BIOS for example, while an ISSU does and it's
non-disruptive with dual-supervisors.
Just to add a data point, it's almost non-disruptive. There's a
noticeable blink on a per-linecard basis, probably <3 seconds, but I've
had to deal with explaining the blip during a "non-disruptive" upgrade.
