Azure Powershell: Az and AzureRM modules cannot be imported in the same session

Question

I have the below script that needs to remove files from an Azure Storage Container that are older than 7 days and it has suddenly stopped working:

$StorageAccountName = "#"
$StorageAccountKey = "#"
$ContainerName = "#"
$CleanupOlderThanDays = [DateTime]::UtcNow.AddDays(-7)
$FolderName = "Daily"

$Ctx = New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey
Get-AzStorageBlob -Container "$ContainerName" -Context $Ctx -Prefix $FolderName/ | Where-Object { $_.LastModified.UtcDateTime -lt $CleanupOlderThanDays } |Remove-AzStorageBlob

It fails now with the below error:

PS C:\backupcopy> .\remove_files_daily.ps1

I tried running Uninstall-AzureRm but I get the following error:

I then tried running Import-Module Az.Accounts and got this:

Does anyone know what I need to do to get this working? I'm running

Major  Minor  Build  Revision
-----  -----  -----  --------
5      1      14409  1005

Solution

You could not mix the Az and AzureRm commands together, change the first line in your script as below, then try it in a new powershell session.

$Ctx = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey

---

If you still get the same error, run a new powershell session as admin, use the command Uninstall-Module as below, then try the script again.

Uninstall-Module -Name AzureRm -AllVersions -Force
