My company would like to perform a system update for our DNA center and I was wondering if there are things I should watch out for since we have a 9800-CL (16.12.4a) Non-Fabric deployment using DNAC.
We are upgrading from 184.108.40.206 to 220.127.116.11. The upgrade guide makes it seem like a walk in the park and I can't find any info regarding pitfalls to keep in mind. Seems to easy which in my experience it usually isn't.
The 9800 controller has has nothing to do with how DNAC is updated. I have done many DNAC system upgrades. I will say they are “that easy” unless you hit a weird bug. However, since your staying in the same train version, you are safe for the system upgrade. Version 18.104.22.168 is a bug release only.
Personally, I would probably skip this step when upgrading to a bug fix release, as you are. I would probably run it when upgarding to 2.2.3.x and definitely run it when upgrading to a new major release like 3.x (whenever that day comes)
