IOS upgrade for ISR4431 with ver 16.9.4 and remain in auto mode

[keith.smith]

My company is current upgrading the IOS of our devices from the older version to the new version for the device using Cisco DNA Center. Some of our ISR routers have version level at 16.9.5. When we update the IOS to 17.9.5, the router goes into controller mode and technical intervention is needed to restore back to autonomous mode. Is there a way to upgrade these devices and have it remain in autonomous mode?

Are you guys loading the right IOS on the DNAC ?  If you are not using SDWAN, you should use the IOS-XE not IOS-XE SDWAN version.

Thanks for the response. The version of IOS we have marked as the golden image is version number is 17.09.05a (isr4400-universalk9.17.09.05a.SPA.bin). This is an IOS XE image, currently not available.

Sounds to me you are using sdwan imagens and thats why the Router is activating the controller mode

How is that possible? The latest IOS XE SD-WAN software is version 16.12.5(MD). I am using 17.9.5a .

Hi Keith did you find the root cause? Have you gone to the TAC?
