Do you mean
without afternoon sun? Succulents love direct sunlight and heat. (All cacti are succulents, but not all succulents are cacti.) Without pictures I'm trying to see in my mind's eye the collapse and cutting of your desert rose (adenium). I will venture to say...allow the top half to callous over for about 5 days, then plant in cactus mix. Moisten the soil lightly and plant it...do not water for about a week.
I seriously doubt the bottom half (the caudex) will grow new stems; but one never knows with these amazing plants. If the caudex is super-soft and you see dark flesh at the cut, then it has rotted and cannot be saved.
Glad you're moving to a place that has an outdoor balcony where your succulents can thrive.
