NetSight inventory manager shows EXOS images as valid for switches that cannot use that version
NetSight inventory manager shows 16.x images as available for upgrade when these switches dont support 16.x but only 21.x and higher. The same for switches that can only use 16.x and lower, 21.x and higher is shown as available for upgrade.
Currently NetSight Inventory manager cannot distinguish between switch platforms and which versions they can and cannot use.
This will be fixed in new relases, the issue is known as CR net0043493 and is scoped to be fixed in 8.0
