How do i transition my baby?

Currently we're cosleeping and have mostly since birth. I breastfeed so its a lot easier that way. But now i feel it could become dangerous. He's started to crawl and sit up by his self. For his naps in the day i put him to sleep in my arms usually nursing then in his play pin or sometimes he falls asleep in his swing. If i start transitioning him to his crib is it going to be hard? Or will it be easier since we don't cosleep for naps? He's 8 months old. I did try a basinet in the beginning and he seemed to be okay with it for about a month and then he wouldn't go for it anymore. If i move his crib next to my bed would it be better for him? Ftm here.
