One of the prerequisites for installing the Dell Technologies component updates is to apply the most current Microsoft Azure Stack Hub software full updates. Microsoft updates must be applied sequentially; they are not cumulative in nature.

This section describes how to update the Azure Stack Hub software. The update package includes security patches, bug fixes, and new features for Azure Stack Hub.

Download and carefully review the associated release notes prior to installation. The notes contain references to known issues that may affect the update. For more information, see Azure Stack Hub Servicing Policy.

Before installing any updates, we recommend, that you run Test-AzureStack -Group UpdateReadiness from the Privileged Endpoint (PEP) to validate the state of the scale unit and resolve any identified issues prior to starting the actual update process. The general process for running Test-AzureStack -Group UpdateReadiness is:

$cred = Get-Credential

$pepsession = New-PSSession -ComputerName x.x.x.x -ConfigurationName PrivilegedEndpoint -Credential $cred

invoke-command -session $pepsession -scriptblock { test-azurestack -group updatereadiness }
