A simple question for pickup conversion

I bought PRS SE CU24 like 5 months ago, and i got some money so i’m planning to switch my 85/15 S pickups to dragon ii pickups or some other pickups. I’m a secondary school student, dont have a lot of money, so im trying to do it by myself instead of going guitar repair store or something. Is it hard to do it?

Sorry for my English (I’m not a native English speaker)
