Nexus 9504 Upgrade

[RICHARD MESSINGER]

Customer has a Nexus 9504 with dual Sup-A+, and it is doing L2/3 for their organization.  they thought that they were safe to be able to do ISSU, but that is not supported.

they are looking at upgrading from 10.3(3) to 10.5(4).

What should the expect for downtime doing the upgrade?

If they had dual 9504's would they be able to do ISSU then?

I have already seen these pages. What I am looking for is some guidance I can provide that will tell the customer that for the Nexus 9504 they have they can expect x minutes of disruption when they do the upgrade.

  - @RICHARD MESSINGER   If you don't have dual supervisors and or can't do ISSU  , expect 30 minutes
                                             for providing the new image to the switch (with the necessary commands) and booting
                                             again ,
