Transition to FP&A from business analyst/data science role

Hi all,
I am a business analyst with three years of experience in SQL,EXCEL,R and python. I am applying for an MBA this fall for the batch starting next fall. My post Mba goal is to work in corporate finance in a FP&A role. I come from a quantitative heavy background of engineering and have a passion for finance. I have acquired knowledge on accounting and corporate finance through online courses. I am also a regular investor on a personal level.
Just wanted to know what can be done to transition in a corporate finance/ FP&A role ? Is Mba the way to go ?
