Race Change, how does it work if the other race hasn't the class available?

Hi, I was asking myself if it is possible to make a race change from a drenai to a dwarf even if the class isn't available for dwarfs. If for example I want to race change my drenai shaman to a dwarf can I still keep the characters class or am I forced to change the class. I searched for answers on the forum but couldn't find one. I prefer to be sure on such a question before doing a race change. I thank in advance for any help on my question.

Race change has the same limitations as creating a character. And it's not possible to change the characters class. In case of draenei shaman, race change is useless since there are no other alliance races that can be shamans.

you are forced to pick only a race which allows to maintain your Class

You can't Race Change to a race that can't be of your character's class.
