To transfer the domain to another registrar, You will need a domain transfer secret (EPP code). You will have to raise a support ticket requesting Mumbai Hosting for the domain transfer secret (EPP code). Mumbai Hosting will charge a one-time support fee to send you the transfer (EPP) code for your domain name.
