How to upgrade eXR by one cmd “install replaced” | NCS5500

Awesome upgrade cmd for eXR, that will help customer simplify upgrade procedure and do upgrade automation! Feature release from 652. Just tested and summarized.

I summarized normal upgrade eXR version by install add/prepare/active at former: Upgrade/Install Packages in eXR. For the article, will summary how to upgrade by install replaced.

“Install replaced” is a new cmd that help customer upgrade only by one cmd, don’t need to add/prepare/active steps, that only support by GISO. What is GISO? That is an image bundle, customer can flexibly customize the image, e.g only bundle: ISIS rpm + mini iso + k9 rpm + configuration to one GISO, more GISO information, please check CCO Doc: Flexible Packaging Configuration Guide for Cisco NCS 5500 Series Routers

PS: “Install replaced” that will not affect running configuration, and auto removes inactive rpm, and commit.
