Identify Yang model changes

[tbf2004]

Hi!

Being a newbie, I was wondering how to spot the Yang model changes between two software releases (IOS-XR 6.7.3 & 7.2.2 for example) for an ASR9K.

Thanks !

I would recommend you to check the YANG-SUITE toolset here: https://developer.cisco.com/docs/yangsuite/#!yang-suite-analytics

and check the "YANG Diffs" application.

That said, if you have built your NEDs in NSO for both versions and loaded them into the system, NSO "migrate" action provides you a dry-run if the modules would have an impact on the current device configuration

admin@ncs(config)# devices device DEVICE migrate new-ned-id NEW_NED_VERSION dry-run verbose
