Get in touch with your Cisco SE or partner. Cisco SE's have access to a conversion tool that takes in an IOS config and spits out an XR config. It's usually about 80-95% correct. It even shows you sections that are not in use and can be removed. On Thu, Aug 31, 2017 at 5:39 AM, Nick Hilliard <nick@foobar.org> wrote:

Cisco offer a doc how to migrate from IOS to XR of about 40pages, but it's quite old (XR 3.2) and not so interesting.
that doc is still relevant.
And how to you manage RPL editing? I mean with IOS you have some completion on TAB keystroke, but as RPL has to be edited within a text editor, you loose this kind of 'help'.
You can edit RPL from the command-line too, with tab completion and inline help.
Maybe we have to re-think our config from scrash
that is a good option in this situation. RPL is significantly more flexible than what's available on vanilla IOS, and you would benefit from learning RPL, then standing back and looking carefully at what you're doing with route routing policy to see how it can be abstracted into well-structured RPL.
There are a number of major new features: RPL functions can call other RPL functions, which you can't really do with route-maps (leading to lots of duplication for similar configuration), and passing variables into RPL functions. You can use these features to build up structured RPL configuration mechanisms which give a lot of flexibility and power.
Also, XR is better from the point of view of automation. If it makes sense to build automation into your network, this would provide a good opportunity.
