SD-WAN image downgrade

[hanumantha.reddy]

am trying to downgrade the Cisco ISR 1121X-8P router from 16.12.3 to 16.10.3a. But its not happening. Can anyone let me know, is there any other way for downgrading the SD-WAN image.

Hello,

Are you doing it from vmanage or from CLI? Are you getting a specific error?

Thanks!

Actually, it doesn't appear that model is supported in 16.10.x code

Release notes for 16.10.x don't show that model:

https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/xe-16-10-18-4/sd-wan-rel-notes-xe-16-10-18-4.html

Release notes for 16.12.x do:

https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/xe-16-12/ios-xe-sd-wan-re-notes-16-12.html

Hope that helps!
