Recently I decided to change domain registrars for all the domains I have. Due to various reasons, my domains are registered through 3 separate registrars, and it made sense to consolidate into a single registrar. Below is the experience I went through, which should be pretty typical of everyone. Winning Registrar refers to the registrar I am transferring the domain to, and Losing Registrar refers to the registrar I am transferring the domain away from.
The steps are as follows:
1. Going into the console of the Losing Registrar, unlock the domain and write down the Auth Code.
