Career Transition from InfoSec to Cloud Engineering

I've been working in Information Security for over 10 years and I feel I've hit a wall. I'm not interested or motivated to climb the ladder and I don't feel my currently role is allowing for me to grow. My day to day is spent figuring out how to solve complex issues but also speaking to people to get buy in on the solutions I think will help. After 5-7 years of doing this type of work, I'm looking to pivot into Cloud Engineering. I'm afraid I will have to start from 0. Any advise for those later career tranisitioners?

P.S. I attached a picture of my dog because he's adorable... why not?
