MBA after Day 1 CPT

Has anyone done an MBA after doing Day 1 CPT Masters? I’m currently on bachelor degree STEM OPT that expires this year December, and I’m considering doing Day 1 CPT to continue employment for about less than a year and go to an MBA after next fall (so I would need to finish the Day 1 CPT in a year, unless I can drop midway? Or transfer from masters to mba?)
