Hi South74,
I'm sorry to reply you late, I made more research on this issue. From what I got so far, this transferring can only be performed via PowerShell cmdlet and it's in Azure.
Please kindly refer to the following article in Github: Getting Started With Azure Domain Transfer from registrar.
Execute the transfer Close all other PowerShell windows and start a new one as an administrator. Navigate to the script directory and run the PS script: cd "C:...\azure-domain-transfer" .\DomainTransfer.ps1 Confirm the transfer When you get the confirmation email. Click the confirmation button Now you have to wait up to 5-7 days for the transfer to be complete.
Accept the transfer from your registrar (if you can) Some registrar let the owner of the domain cancel or confirm the transfer. It allows the operation to be completed before the 5-7 days.
Wait for the transfer to be complete... Wait and check the resource to be fullly available in you Azure portal.
Note: Currently you can only buy a domain from Office 365 but you can’t transfer your domain to as an Office 365 domain registrar as Wild West Domains LLC.
Best,
Shawn
