Introduction

This document describes how to run Upgrade Readiness validation in Cisco DNA Center 2.3.5.x.

Background

Prior to Cisco DNA Center 2.3.5.x, the AURA tool was used to assess the Upgrade Readiness of a cluster. With Restricted Shell fully implemented in 2.3.5.x, most of the AURA upgrade checks are now implemented in Cisco DNA Center. This document provides step-by-step instructions of how to check the Upgrade Readiness of a cluster.

How to run Upgrade Readiness

Upgrade Readiness is part of multiple new validation tools on the System Health page.

1. From the Cisco DNA Center GUI's hamburger menu, click System > System Health.

2. In the upper right hand corner of the System Health page, click Tools and select Validation Tool.

3. If you are running the Validation Tool for the first time, click on "New Validation Run" then go to Step 5.

4. If you have run any validations in the past, click Add.

5. On the New Validation Run page, enter a name, check the Upgrade Readiness Status box then click Run.

6. The validation run typically finishes in a minute. Refresh the browser to show the latest status. Here a completed validation run is displayed.

7. The status column indicates if there are any errors, warning or other information. Click on View Status.

8. If the status of each of the validation tests is "information," please proceed to upgrading the cluster. If there are any errors, please correct them before doing the upgrade. This report can be exported by clicking Export in the top right corner. The report is downloaded as a PDF file and can be reviewed with the TAC if needed.
