[ANSWERED]Creating a Death Knight..

So i was wondering since when you try to create a DK it prompts a window saying: "You must have an existing character of at least level 55 on any realm to create a Death Knight".
Can i level a character all the way to 55 in Icecrown for example and then be able to create a Death Knight in Lordaeron?
I know that the prompt says it so but since i have some characters that are level 80 from Blackrock PVP realm, and i can't create a DK on Lordaeron server wich is what i aim to play on, i was wondering if it is possible...
Ty in advance.

Greetings,

No, that cannot be done, you need a level 55 character on that realm.
