Information About Cisco Catalyst SD-WAN Control Components Upgrade Workflow
Minimum Supported Version: Cisco Catalyst SD-WAN Control Components Release 20.18.1
A Cisco SD-WAN Control Components upgrade workflow is a process that:
-
integrates the software image upgrade of the Cisco SD-WAN Control Components—Cisco SD-WAN Manager, Cisco SD-WAN Controller, and Cisco SD-WAN Validator, and
-
reduces the complexity of upgrading each Cisco SD-WAN Control Component separately.
The workflow upgrades the Cisco SD-WAN Control Components in the following sequence:
-
Cisco SD-WAN Manager
-
Cisco SD-WAN Validator
-
Cisco SD-WAN Controller
In the workflow, you can download software images from the Cisco Software Download repository and upload software images from a local drive.
During the upgrade process, you can monitor the progress for each control component separately.
Information About Patch Release Upgrade For Control Components
A patch release upgrade is a targeted update that addresses specific bugs and introduces minor improvements to the software. It is designed to complement the existing software.
You can apply a patch release upgrade only to its compatible software release version. For example, if your software version is 20.18.1, you can apply patches designed only for 20.18.1. A patch release image is named as a 6-tuple, with the last digit indicating the patch number (e.g., 20.18.1.0.0.1). It is applied on a compatible base 5-tuple release version (e.g., 20.18.1.0.0)
