How to disable ap rolling upgrade in DNAC

 - @palani2010           Do  you have a reason for that question?

It takes so much of time and from secondary wlc connected APs are not moving to primary wlc APs completely

as per my testing it took for me 3 minutes to move to N+1 (compare to SSO HA)

check the fail-over times :

  - @palani2010     How did you come to those conclusions ? What commands did you use ? What logs did you inspect ?

From DNAC as i remember, default is 15% i do not remember you can set that none.

May be command Line you can do i guess one hit upgrade.

again as asked before, what is the reason to disable, the feature is good (but most of the time when you do ISSU upgrade) that reboot all AP anyway (that feature never worked for me as expected).

You can not have different version of code WLC and AP to work as expected.

Rolling AP Upgrade disable on Primary WLC on DNAC for N+1 deployment

Note - Rolling AP upgrade disabled on secondary WLC (We have downtime as we have many APs in our environment)

suggested method is from CLI :
