I've been trying to repot all new to me succulents regardless of how I acquired them. I take cactus/succulent mix and add 30-50% perlite after reading here and elsewhere about people doing the same. The only ones that don't get repotted soon after I get home are those which have been watered and anything in flower. Those which have been watered are usually removed from the plastic pot and left to dry. Dry soil seems easier to remove than wet.
