Anyone went on mavenclad after tysabri?

I’ve been on tysabri 18 months (every 4 weeks, subcutaneous) and I am experiencing a lot of joint/muscle pain in my lower back and pelvis after the injection so I told my neurologist I was considering moving to mavenclad.
She strongly rejected the idea saying people like me who had a lot of brain inflammation didn’t do well under mavenclad and that I’d probably get a lot of new lesions if I stopped tysabri (note: my condition is stable, no more new lesions and no symptoms, etc.)
She said mavenclad isn’t as efficient as people seem to think.
Has anyone experienced going from tysabri to mavenclad and would you mind sharing your experience?
Thank you!
