Realm transfer closed?

Hi, I just started playing the game yesterday and I noticed my realm is Onyxia and I want to transfer to Icecrown.

I'm trying to follow these steps but can't find anything. Is real migration closed??

1. Log in to your account on the WoW website.
2. Go to "My Account" > Services > Select your realm and character.
3. Choose "Realm transfer" from the fourth fall menu.

There's no migration available yet. It's only available at the end of Onyxia's lifespan.

Thank you. It looks I will need to create a new char.
