What is the process to upgrade existing Azure VM agent after provisioning - Microsoft Q&A (2024)

Use PowerShell to inventory the current version of the Azure VM Agent installed across all VMs.

$Report = [System.Collections.Generic.List[Object]]::new() $vms = $null $vms = Get-azVm -Status Foreach ($vm in $vms){ $obj = [PSCustomObject][ordered]@{ "Server Name" = $vm.Name "OS" = $vm.StorageProfile.ImageReference.offer "OS Sku" = $vm.StorageProfile.ImageReference.sku "OS Name" = $vm.OsName "OS Version" = $vm.OsVersion } $report.Add($obj) }$Report | Export-CSV C:\temp\ArchieVM_Status.csv

This can be run against any subscription to retrieve Azure VMs and their corresponding operating systems.

NOTE: The OS Name and OS Version will not be populated if the VM is turned off/deallocated.

Download the latest version of the VM Agent from the https://github.com/Azure/WindowsVMAgent.

Deploy this via automation tools (like Azure Automation, PowerShell, Desired State Configuration (DSC), or Group Policy) to manage updates across multiple VMs efficiently.
