IOS XE to IOS XR

[cmandela]

Which tool can I use to change IOS XE configs to IOS XR configs?

[cmandela]

I have ASR1k and I want to replace it with ASR9901

Hi @cmandela ,

There is an internal tool at Cisco called SoX that is used for that purpose. It is unfortunately not available externally, but if you open a TAC case, a TAC engineer will be able to convert the configuration file for you.

I can confirm that the Cisco-internal tool SoX is still in-use and Cisco support can translate XE configs into XR configs. There is some level of sanity-checking involved and it may not match your intent, but it saves a LOT of time to get the base XR template from XE, which can be modified. 

We had a Cisco XE specialist and an XR specialist on a phone call during a regular sync meeting with Cisco at our company, and they collaborated and provided an output XR file using SoX based on an XE config that I gave them. They provided this file same-day, so it appears to be a quick process.
