To execute the transfer, first, unlock and request an EPP code for the domain from your current provider.
Once you have the code you can follow these steps in the control panel of your hosting account with

1) Go to My Domains > Registered Domains

2) Click on “Register/Transfer Domain”.

3) Enter your domain name and click “Transfer”. You should be brought to a checkout page that has a space for the EPP code.

It may take a few hours to a day or so to transfer the domain name. It needs to be released by the current provider and accepted by the new provider.

Once it is transferred over make sure to check and update your ownership information and keep it up to date.
