Can we transfer character from Lordereon to Deathwing or Ragnaros?

Hello! My question is in the title. I though it was possible and now that I'm trying, I can't find a way to transfer character from Lordereon to Deathwing or Ragnaros?

So, is it possible or?

Thanks a lot and sorry for this topic. I hope that could help others too.

Lordaeron is a test realm currently. All characters in it will be deleted, possibly more than once, and for sure before the official release.
There are no transfers out of a test server to production ones.
