I can confirm this is true. I've done it before with several other characters as long as they are all on the same server you are transferring them from. (Say all of them are on Cactaur, you can transfer them. If one is on Cactaur and another on Siren, you have to pick which one since you can't use it on both of them.)
I hope that helps!
