Methods for Shrinking Disk Size in Azure

Question

Increasing disk size is easy, but is there any method to shrink disk size when we no longer require large disks? This is applicable in different cases. For example, I have a Linux VM on VMware with a 1024 GB disk. When I transfer it to Azure using Veeam Backup & Replication software, I see the VM disk on Azure is 1025 GB, and it picks a 2048 GB disk on Azure as the OS disk, which incurs unnecessary costs.

Unfortunately there is not an automatic way to decrease the size of an Azure Disk. The recommended method is to create a new disk and copy the contents, you will also need to shrink the partition before copying. With the OS disk there is some added complexity of this. Please check this thread where we have some details on how this might be accomplished.
