C9500-16-X-A IOS and rommon upgrade

[Neri Gary Cacatian]

Hi,

I recently installed a catalyst 9500-16-x-A. I was wondering how do we perform IOS upgrade from 16.9.5 to 17.3.5? Would the rommon be upgraded as well when we upgrade the IOS? my current rommon version is 16.9.1r my desired version is 17.3.2r.

Another thing is how do we perform dna license registration for this switches, currently showing as evaluation.

BTW my switch is already on virtual stack

Direct upgrade from 16.9.5 to 17.X.X is supported, however, I recommend waiting for another 3 weeks for 17.6.5 to drop. 

Also, I recommend 17.6.X over 17.3.X.

Watch the upgrade from 16.X.X to 17.X.X.  There will be an automatic micro-code upgrade.
