How to transfer existing domain name?

You need to get an Authorization (Auth/EPP) code from your current domain/hosting provider;
(This code may also be called an "EPP code" or "transfer key/code" or "secret key/code". You may find this code in your current provider’s settings, or you can request a code from your current provider. Sometimes, it may take a day or two to get this code, so we recommend requesting it right away. Make sure that your domain is unlocked from transferring by asking your current domain provider about it).
Go to My Websites;
Click "Add domain" link;
Choose "Transfer your domain" option;
Insert your domain and press "Transfer" button;
(While transferring, keep in mind, that you will need to pay the domain transfer fee according to the prices).
Insert the Authorization (Auth) code and press "Continue" button
Fill in the following details for your domain (you can choose an existing contact or create a new one):
- Domain Registrant/Owner
- Administrator contact
- Billing contact
- Tech contact
and press "Transfer" button.
