[c-nsp] Upgrading from 3.0.6 to Denali-16.3.5b

[Christina Klam]

All,

This is the second Cat3850 that I have tried to upgrade to Denali-16.3.5b.  Both take hours to go from expanding the files to finishing.  I am on hour two for the second switch.  Except for interface status messages about my management port (Gig 0/0), there is nothing going over the console.  I am just assuming that the upgrading is indeed happening.  When I did the first switch, it took hours as well, so I will be patient.  But I am not happy.

Fortunately, I have the luxury that these two switches were/are not in production at the time of their upgrades.  However, I will not have the luxury for the other 3850s.

What is your experience with upgrading to Denali or Everest?   This is beyond ridiculous.  

Regards,
Christina
