First of all am aware characters cant be transfered from one server to the other or deleted characters be restored etc.
However is it possible to transfer a character from one account to another account on the same server and same realm e.g.
//////////////// BEFORE TRANSFER\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
ACC -1 ----> BD, Druid
} same server, same realm
ACC -2 ----> Priest
from scenario above, can BD be transferred from ACC -1 to ACC -2 e.g.
//////////////// AFTER TRANSFER \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
ACC - 1 ----> Druid
} same server, same realm
ACC -2 -----> Priest, BD
I think its possible but will demand database transaction
