Getting 19mo from my bed into his own?

So my youngest is 19 months old and he's slept in my bed since he was 1 month old. I'm pretty sure hes too old for the CIO method etc etc but does anyone have any tips for getting him in his own bed? His toddler bed is currently in his big brothers room (3years) but I can move it in my room to begin with if need be :) I'm due baby #3 in June so thought now is better late than never! Thanks in advance.
