Deleting the Deployed BPM in PI

Hi Experts,

I need to delete the current deployed BPM in PI, and re-develop as I want change the naming of Software component and product.

Current I developed  BPM with mulpile processes for each requirement, which I would like separate to make any changes independent AS I THINK WE CAN ONLY BUILD AND DEPLOY COMPLETE PRODUCT.

We are using release NW 7.31 SP06 as part of PO(PI+NW BPM).

Appreciate your responses on how to achieve above with any alternatives.

Thanks,

Hussein
