Breaking changes for Az 1.0.0

This document provides detailed information on the changes between AzureRM 6.x and the new Az module, version 1.x and later. The table of contents will help guide you through a full migration path, including module-specific changes that may affect your scripts.

For general advice on getting started with a migration from AzureRM to Az, see Start migration from AzureRM to Az.


There have been breaking changes between Az 1.0.0 and Az 2.0.0 as well. After following this guide for updating from AzureRM to Az, see the Az 2.0.0 breaking changes to find out if you need to make additional changes.

General breaking changes

This section details the general breaking changes that are part of the redesign of the Az module.

Cmdlet Noun Prefix Changes

In the AzureRM module, cmdlets used either AzureRM or Azure as a noun prefix. Az simplifies and normalizes cmdlet names, so that all cmdlets use 'Az' as their cmdlet noun prefix. For example:


Has changed to:


To make the transition to these new cmdlet names simpler, Az introduces two new cmdlets, Enable-AzureRmAlias and Disable-AzureRmAlias. Enable-AzureRmAlias creates aliases for the older cmdlet names in AzureRM that map to the newer Az cmdlet names. Using the -Scope argument with Enable-AzureRmAlias allows you to choose where aliases are enabled.

For example, the following script in AzureRM:

#Requires -Modules AzureRM.Storage
Get-AzureRmStorageAccount | Get-AzureStorageContainer | Get-AzureStorageBlob

Can be run with minimal changes using Enable-AzureRmAlias:

#Requires -Modules Az.Storage
Enable-AzureRmAlias -Scope Process
Get-AzureRmStorageAccount | Get-AzureStorageContainer | Get-AzureStorageBlob

Running Enable-AzureRmAlias -Scope CurrentUser will enable the aliases for all PowerShell sessions you open, so that after executing this cmdlet, a script like this would not need to be changed at all:

Get-AzureRmStorageAccount | Get-AzureStorageContainer | Get-AzureStorageBlob

For complete details on the usage of the alias cmdlets, see the Enable-AzureRmAlias reference.

When you're ready to disable aliases, Disable-AzureRmAlias removes the created aliases. For complete details, see the Disable-AzureRmAlias reference.


When disabling aliases, make sure that they are disabled for all scopes which had aliases enabled.

Module Name Changes

The module names have changed from AzureRM.* to Az.*, except for the following modules:

AzureRM module Az module
Azure.Storage Az.Storage
Azure.AnalysisServices Az.AnalysisServices
AzureRM.Profile Az.Accounts
AzureRM.Insights Az.Monitor
AzureRM.DataFactories Az.DataFactory
AzureRM.DataFactoryV2 Az.DataFactory
AzureRM.RecoveryServices.Backup Az.RecoveryServices
AzureRM.RecoveryServices.SiteRecovery Az.RecoveryServices
AzureRM.Tags Az.Resources
AzureRM.MachineLearningCompute Az.MachineLearning
AzureRM.UsageAggregates Az.Billing
AzureRM.Consumption Az.Billing

The changes in module names mean that any script that uses #Requires or Import-Module to load specific modules will need to be changed to use the new module instead. For modules where the cmdlet suffix has not changed, this means that although the module name has changed, the suffix indicating the operation space has not.

Migrating #Requires and Import-Module Statements

Scripts that use #Requires or Import-Module to declare a dependency on AzureRM modules must be updated to use the new module names. For example:

#Requires -Module AzureRM.Compute

Should be changed to:

#Requires -Module Az.Compute

For Import-Module:

Import-Module -Name AzureRM.Compute

Should be changed to:

Import-Module -Name Az.Compute

Migrating Fully-Qualified Cmdlet Invocations

Scripts that use module-qualified cmdlet invocations, such as:


Must be changed to use the new module and cmdlet names:


Migrating module manifest dependencies

Modules that express dependencies on AzureRM modules through a module manifest (.psd1) file will need to updated the module names in their RequiredModules section:

RequiredModules = @(@{ModuleName="AzureRM.Profile"; ModuleVersion="5.8.2"})

Must be changed to:

RequiredModules = @(@{ModuleName="Az.Profile"; ModuleVersion="1.0.0"})

Removed modules

The following modules have been removed:

  • AzureRM.Backup
  • AzureRM.Compute.ManagedService
  • AzureRM.Scheduler

The tools for these services are no longer actively supported. Customers are encouraged to move to alternative services as soon as it is convenient.

Windows PowerShell 5.1 and .NET 4.7.2

Using Az with PowerShell 5.1 for Windows requires the installation of .NET Framework 4.7.2. Using PowerShell Core 6.x or later does not require .NET Framework.

Temporary removal of User login using PSCredential

Due to changes in the authentication flow for .NET Standard, we are temporarily removing user login via PSCredential. This capability will be re-introduced in the 1/15/2019 release for PowerShell 5.1 for Windows. This is discussed in detail in this GitHub issue.

Default device code login instead of web browser prompt

Due to changes in the authentication flow for .NET Standard, we are using device login as the default login flow during interactive login. Web browser based login will be re-introduced for PowerShell 5.1 for Windows as the default in the 1/15/2019 release. At that time, users will be able to choose device login using a Switch parameter.
