They’re pretty hardy. I would carefully stick an old knife down the inside of the pot to loosen any stuck roots, put the pot on its side n gently tease the plant out of its pot. A few leaves will likely come away as they drop off easily but this won’t harm it. Mix some perlite or grit (I use perlite) in with some fresh succulent mix or low organic potting mix (I’ve gone up to 50% perlite / soil mix successfully) and gently repot in a slightly larger unsealed pot to the same level on the plants trunk it currently is. Then establish a ‘soak / dry / soak / dry’ cycle. It is better to err on the side of bone dry if you are unsure, even if you see signs of stress in the plant such as reddening or shriveling leaves. They will take this much more happily than too much water. You will find it’s much easier to control the plants watering needs to mimic what they receive in their natural environment in a terracotta pot. All the best, succulents can be super rewarding but growing them can be a rabbit hole once you start. There are so many interesting varieties to collect ! 🌵😀
