Stop Virtual Machine

Stop the virtual machine from migrating

Click Stop on the Virtual Machine that should be migrated.

Enable the Export function to generate a single URL containing the VHD of the managed disk to migrate.

On the selected virtual machine, click on Disks
Select the managed disk that you want to migrate
Click Export
Click on the Generate URL button
Copy this unique URL pointing to the target VHD file to the Notepad or any other clipboard.

Create a storage disk in the target region of the new or existing subscription.

So now, we need to create a storage account in the target region on the target subscription
Create a Container containing the VHD file to use and retrieve the connection information to that storage account:
- On the Azure portal, select All Services.
- Scroll to storage, and then select storage accounts
- On the Storage Accounts window, click Add
- Select the subscription in which you want to create the storage account, as well as the target resource group
- Enter the name for your storage account
- Select the location of your storage account (target region)
- Leave all other fields to their default value
- Click Verify + Create to review your storage account settings and create the account.
After the storage account is created, click Blob on the container
On the Name field, type VHDs
Click the OK button to confirm. This folder will contain the VHD file copied to the new region.
Click VHDs and then select Properties
Copy the URL to Notepad
Click access keys and copy the Key1 key to the Notepad.

Use AzCopy

Use an Azure Virtual Machine to copy the data (VHD File) from a Managed Disk to a new storage account in the target subscription. This will reduce copy time. You can copy data between a file system and a storage account, or between storage accounts.

Run a command prompt from the Azure virtual machine
Select the C:\Program Files (x86) \microsoft SDKs\Azure\AzCopy Directory
Type the command to copy the data from the source managed disk to the target storage account previously created in a target subscription.
Don’t forget to add a file name that ends on .vhd.

azcopy /source:”<URL_FROM_VHD>” /dest:”<URL_VHD_DESTINATION>” /destkey:”<KEY1>”

Progress:

During the copy you will see the file and the transfer rate in Mbps
