EB2 and EB3 for Same Company

Hi All,

I have Approved EB2 with PD 2017. Since i am seeing EB3 is moving faster. Can i apply for EB3 also with the same company ? Company is ready to do but don’t know is this possible. If possible what is the process for EB3 if EB2 is already approved ?
Note : I am not going to Port the date & this question is not related to EB2 to EB3 downgrading.

Thanks a lot
