Copy managed disks in the same subscription or different subscription with PowerShell
This script creates a copy of an existing managed disk in the same subscription or different subscription. The new disk is created in the same region as the parent managed disk.
If needed, install the Azure PowerShell module using the instructions found in the Azure PowerShell guide, and then run
Connect-AzAccount to create a connection with Azure. Also, you need to have an SSH public key named
id_rsa.pub in the .ssh directory of your user profile.
This article has been updated to use the new Azure PowerShell Az module. You can still use the AzureRM module, which will continue to receive bug fixes until at least December 2020. To learn more about the new Az module and AzureRM compatibility, see Introducing the new Azure PowerShell Az module. For Az module installation instructions, see Install Azure PowerShell.
