Introducing the new Azure PowerShell Az module

Starting in December 2018, the Azure PowerShell Az module is in general release and now the intended PowerShell module for interacting with Azure. Az offers shorter commands, improved stability, and cross-platform support. Az also offers feature parity and an easy migration path from AzureRM.

With the Az module, Azure PowerShell is now compatible with PowerShell 5.1 on Windows and PowerShell Core 6.x and later on all supported platforms - including Windows, macOS, and Linux.

Az is a new module, so the version has been reset to 1.0.0.

Why a new module?

Major updates can be inconvenient, so it's important that we let you know why the decision was made to introduce a new set of modules, with new cmdlets, for interacting with Azure from PowerShell.

The biggest and most important change is that PowerShell has been a cross-platform product since the introduction of PowerShell Core 6.x, based on the .NET Standard library. We're committed to bringing Azure support to all platforms, which means that the Azure PowerShell modules needed to be updated to use .NET Standard and be compatible with PowerShell Core. Rather than taking the existing AzureRM module and introduce complex changes to add this support, the Az module was created.

Creating a new module also gave our engineers the opportunity to make the design and naming of cmdlets and modules consistent. All modules now start with the Az. prefix and cmdlets all use the Verb-AzNoun form. Previously, cmdlet names were not only longer, there were inconsistencies in cmdlet names.

The number of modules was also reduced: Some modules which worked with the same services have been rolled together, and magement plane and data plane cmdlets are now contained all within single modules for their services. For those of you who manually manage dependencies and imports, this makes things much simpler.

By making these important changes that required building a Azure PowerShell module, the team has committed to making it easier than ever, and on more platforms than previously possible, to use Azure with PowerShell cmdlets.

Upgrade to Az

To keep up with the latest Azure features in PowerShell, you should migrate to the Az module as soon as possible. If you're not ready to install the Az module as a replacement for AzureRM, you have a couple of options available to experiment with Az:

  • Use a PowerShell environment with Azure Cloud Shell. Azure Cloud Shell is a browser-based shell environment which comes with the Az module installed and Enable-AzureRM compatibility aliases enabled.
  • Keep the AzureRM module installed with PowerShell 5.1 for Windows, but install the Az module for PowerShell Core 6.x or later. PowerShell 5.1 for Windows and PowerShell Core use separate collections of modules. Follow the instructions to install PowerShell Core and then install the Az module from a PowerShell Core terminal.

To upgrade from an existing AzureRM install:

  1. Uninstall the Azure PowerShell AzureRM module
  2. Install the Azure PowerShell Az module
  3. OPTIONAL: Enable compatibility mode to add aliases for AzureRM cmdlets with Enable-AzureRMAlias while you become familiar with the new command set.

Migrate existing scripts to Az

The Az module has a compatibility mode to help you use existing scripts while you work on updates to the new syntax. Use the Enable-AzureRmAlias cmdlet to enable the AzureRM compatibility mode. This cmdlet defines AzureRM cmdlet names as aliases for the new Az cmdlet names.


Even though the cmdlet names are aliased, there may still be new (or renamed) parameters for the Az cmdlets that will be exposed. Don't expect enabling aliases to take care of the full migration for you! After enabling them, test your scripts to make sure they don't need any immediate updates.

The new cmdlet names have been designed to be easy to learn. Instead of using AzureRm or Azure in cmdlet names, use Az. For example, the old command New-AzureRMVm has become New-AzVm.

For a full description of the migration process, see Migrate from AzureRM to Az.

Continued support for AzureRM

The existing AzureRM module will no longer receive new cmdlets or features. However, AzureRM is still officially maintained and will get bug fixes up through at least December 2020.

The Az module is production-ready, in GA, and does not incur any additional costs on Azure. We recommend that you switch to the Az module as soon as possible to keep up with the latest Azure features.
