trying to upgrade a 9500 stack in ISSU mode using DNA. I am getting an error on prechecks that the compatibility matrix needs to be uploaded. I uploaded the latest 17.7.1 and get an error in DNA. I want to upgrade from 17.3.3 to 17.3.4.
You'll want the matrix specific to 17.3.4. It looks like it was removed, but that was a mistake. I've notified the team responsible so they can put it back.
I'm told that the minimum version that Cisco DNA supports for SWIM ISSU is 17.6.1, though I don't see any external documentation for that. If you want to use ISSU, you'll have to do the process manually until you reach 17.6.1 or later.
