Dk Instant 80

Hello guys, at fiirst i hope there is no double post now, but i couldn´t find a topic like this.
My Question is, is it possible to boost an instant 80 DK without having a Charakter on lvl 55 ?
I think it is fair enough to pay for 20 Coins isn`t it ?
Hope for help, woulde be nice if its possible! ;)

If you're playing on Icecrown, yes, you can skip the level 55 prerequisite to create a Death Knight. If you're playing on Lordaeron, however, it is not possible to boost a character or create a Death Knight without a level 55.
