It's different. Complexity lies elsewhere. Transition is definitely possible, but, as always with stack changes, get ready to be in heavy learning mode again. At many places (I'd say the right ones, but I'm biased) when backend engs talk about ownership they mean end-to-end ownership, meaning undestanding how to run and operate their services, meaning you'd need to learn about infrastructure as well (the famous 'devops' thing, but don't get me started on terminology).
