One thing to think about - are you looking to transition in your current company or in a new company? I'm a PM at Google. One thing that works here is having eng do 20% PM projects or do a PM rotation for a few months to get a taste for the life before committing fully. I don't know how it works at your company but you could look into taking on some PM responsibilities before making the move. A certification may explain more about the role and give you background knowledge, but it wouldn't help in skill development IMO. The best way to learn PM'ing is to do it. And if you're interviewing for a PM role, it's much better to talk about actual work than certifications. Lastly, age is not an issue and it's probably better if you have more industry experience before moving to a PM role. Of course, these are my opinions and not that of Google, etc.
