Usually when stuffing my accounts full of unconverted goodness I move one pet a month (or every few months, depending on how I acquired the pet).
I've also put some badass pets with an UC that I'm moving "UFA" and taken applications... chosen true new owners for Draiks / BN UCs / whatever and moved my prized pet to my own account. /shrug

Yeah, the IP manipulation is a must-have... just sayin'.
Just do it one over 6 months, choosing elite proxies in different regions, though for each account, I'd choose IPs in the similar area. During the transfer, get one account to NM the other with different typing styles over how you totally want to adopt it so much.
