JN0-422 Retirement: Transitioning to the New JN0-423 Exam in 2025

Juniper Networks is refreshing its certification program for network automation and DevOps professionals. As part of this update, the JN0-422 Automation and DevOps, Specialist (JNCIS-DevOps) exam will be retired on October 5, 2025. Its replacement, the JN0-423 exam, brings a sharper focus on modern tools and protocols, ensuring that certified engineers stay aligned with industry advancements.

Why Juniper Is Retiring JN0-422

The automation landscape is evolving rapidly. New frameworks, APIs, and orchestration tools are shaping how engineers build and manage networks. Juniper's move to retire JN0-422 and introduce JN0-423 ensures that its JNCIS-DevOps certification measures the skills most needed in today’s production environments - and in the years ahead.

What JN0-422 Covered

The JN0-422 exam validated intermediate-level knowledge of Junos automation and related technologies. Its topics included:

●Platform Automation Overview

●NETCONF/XML API

●Data Serialization and Templating

●Python

●Automation Frameworks

●Junos Automation Scripts

●YANG/OpenConfig

This blueprint emphasized Python scripting, XML-based APIs, and templating for configuration management.
