Additional Information

Insight Into Step 3: If you do not see the Zone Transfer tab, it is likely a permissions issue. Though admins and technical users can see zone transfer tabs on a domain-by-domain basis, only the account owner/Primary user (one user only that exists at a higher permissions level than Admins) can see this tab. 

If you do not know the Primary User for an account you have access, Customer Support provide contact info to you.
