azure powershell - az replace AzureRM

You may have seen or used Azure PowerShell commands that used a -AzureRM format. In October 2018 we announced the replacement of the AzureRM module with the Az module. This new module has several features, notably a shortened cmdlet noun prefix of -Az instead of -AzureRM. The Az module ships with backwards compatibility with the AzureRM module so the -AzureRM cmdlet format will work, but you should transition to the Az module and use the -Az commands going forward.
