Recovering an Old Friend - Ragnaros Server

Hi,

I've been playing in Warmane since 2011 (back when it's called, Molten WoW). Molten server was the first WoW server who showed me how cool World of Warcraft is, despite all the bugs back then it was still the most enjoyable online game I've ever played in my entire life.

During the server crash of Molten/Warmane, I've lost my good friend (Bullworth-Protection and RETPally) in my Ragnaros server due to me not knowing there was a server crash (I stop playing to focus on my final test and been so long ever since). Bullworth is the only high geared character I have in WotLK and the only character who've faced The Lich King.

I know it's a small chance, but is there a way to recover my Paladin and transfer it to Icecrown server? I've been through a lot with that character and I hope I can meet and play the game using him again.

Thank you.
Cheers.
