If they are bonded to one person, they should be willing to walk on you, sniff you and they should be friendly with you pretty fast. You shouldn't have to do much at all....if they are friendly.
Otherwise, I would start slow, talk to them in the cage, give them about three days or so to get used to a new house. then get a glider SAFE small room/tent, and sit with them, let them run around, maybe run on you. You could, during the DAY, put them in a bonding pouch and let them sleep with you. I wouldn't do the pouch at night, as they are usually awake and active, they won't be happy in the pouch.
at 7am, our colony is awake and active 9am asleep for the day, at 9pm they are getting up and getting active.
don't try to pick them up if they don't like it. instead, try to get them to
walk on you on their own. I put my arm or hand lower then them when they are on cage wall and try to come up slowly so they will walk on my hand. or offer them a treat but have it just far enough away they have to step on your arm to get it.
your looking to build a trust in each other, them trusting you, you trusting them. it can be a slow process.
When we got sophie, she jumped on my wife's shoulder, checked things out, then moved to my shoulder, checked things out. and that was it, no biting, easy pickup, friendly. big mama was almost the opposite.
