depends. today I tried to clone my disk to a new (larger) SSD but I wasn't able to resize the partition, probably because it's encrypted. if not then it might be fairly easy. look into cloning your drive with dd
or similar.
I switched from Linux Mint to Solus on my home computer this week and it was relatively painless (just reinstalled the packages I needed and copied things from my old home directory). your mileage may vary of course 😁
