That's a pretty good question, and I would like to give my 2cs in some of your points
- Try to go to freelancing. There you might be able to move to calmer waters. Especially after you have been considered to old by your permanent employer.
I don't want to think the freelance world is where all the old dinosaurs go to rest in peace, freelance world is more than that, and is pretty far to be calmer waters, You need to focus on selling your own product, yourself, that means be even more competitive than when you are permament, trainings, networking, selling strategies, of course travelling, etc.
- Try to go to management. In management experience is very important, I think, and you don't need to be that up-to-date with modern technologies.
To me that's a big mistake and it's one of the bigest mistakes of the top 5 IT companies does, management is not just a matter of experience, you must really want to do it, you must have the skills to do it or at least be prepared/open to invest on those, I'm talking about soft skills, you'll stop dealing with users-machine and start to deal people whom has it's own problems, objectives, ambitions, talent, etc. be a manager is a hell of a job and you must be really prepared for it, IMHO it's not a natural step of the evolution of a consultant/developer.
- Try to do something completely new. So you could move away from the field of SAP and start a completely new career. Of course this could be difficult.
I love that! When I was 5 years old and people asked me, what do you want to work when you grow up? Well, I'll probably said "I want to be Batman" or a pirate, etc. but what I'm really sure is I didn't say SAP consultant,
I'm not planing to be a grandpa suited on a skinny superhero costume and beat up the bad guys (I'll probably won't look good and I'll get beaten for sure 
) but maybe I'll try to reach my younger self again and ask him "whatcha wanna do?"
Cheers!
