Due to a number of security concerns, it was imperative to get a few Nutanix Prism Central upgraded to a recommended release. At the time of this writing, the release PC.2021.3 was used for this upgraded which was released on April 12th, 2021.
Following Nutanix best practices, we will first initiative a Nutanix Cluster Check (NCC) in Prism Central. This is done by logging into Prism Central and completing the following steps:
- Navigate to Home -> Health
- Click on ‘Run NCC Checks’
- Click ‘Run’
- Once this completes and shows 100% health check, you can proceed with the upgrade.
To begin the Prism Central upgrade, click on the settings gear in the upper-right hand corner. In the ‘Settings’ panel, click on ‘Upgrade Prism Central‘.
The current version will be displayed as well as the available compatible versions. Click on ‘Download‘ to start the Prism Central upgrade download. Then click ‘Yes’ to proceed and then ‘Continue’. Then click on ‘Upgrade Now’ to start the upgrade.
There will be an installation progress bar shown on the screen. This maybe interrupted during the upgrade due to the fact that the Prism Central server will restart during the upgrade. Once it has completed, the page should refresh and prompt for the Prism Central logon page.
Log back into Prism Central and you will be prompted with an upgrade prompt. Click Yes to confirm and refresh the page. Then check the status of the upgrade to confirm it is showing the correct current version and shows 100% with no errors.
