BOA Heirloom equipment

i have some BOA equipment on ragnoros that i want to switch over to lordaeron but i cant do it via in game mail. are heirlooms realm transferable?

1. Lordaeron has no Heirlooms at the moment, at all;
2. Only starting with Mists of Pandaria players were able to send items to different servers.

ah thanks for the reply. i just started playing again, but i was from the molten days so a lot has changed since then i guess
