In August 2018, a new Az PowerShell module was released, combining the functionality of the AzureRM and AzureRM.Netcore modules.

Az module was designed to work on both PowerShell 5.1 and PowerShell Core, so managing Azure resources will always be in sync and up to date no matter the platform you’re working on, latest Azure tooling in every PowerShell.

Another reason for this module to come up is that now Azure Cloud Shell runs PowerShell Core. This implies AzureRM is not compatible anymore.

If you want to use this Az module, it’s imperative to remove all AzureRM modules before installing AZ. I did it using this function from Microsoft you can check here: Uninstall the Azure PowerShell module; let’s see the process I followed:

Check for the current version of AzureRM module

As normally is constantly being updated, it was a good idea to check for the current version, this way:

Get-Module AzureRM -List | Select-Object Name, Version, Path

Uninstalling AzureRM module

function Uninstall-AllModules {



  $AllModules = @()

  'Creating list of dependencies...'
  $target = Find-Module $TargetModule -RequiredVersion $version
  $target.Dependencies | ForEach-Object {
    $AllModules += New-Object -TypeName psobject -Property @{name=$; version=$_.requiredversion}
  $AllModules += New-Object -TypeName psobject -Property @{name=$TargetModule; version=$Version}

  foreach ($module in $AllModules) {
    Write-Host ('Uninstalling {0} version {1}' -f $,$module.version)
    try {
      Uninstall-Module -Name $ -RequiredVersion $module.version -Force:$Force -ErrorAction Stop
    } catch {
      Write-Host ("`t" + $_.Exception.Message)

I simply copied and pasted the code into a PowerShell session:

Then, removed older version of AzureRM module using this function:

Uninstall-AllModules -TargetModule AzureRM -Version 6.7.0 -Force

After that, I double checked that it was correctly uninstalled:

And finally, I was able to install Az module properly:

Install-Module -Name Az -AllowClobber
