How to remove the local sponsor of an LLC company and make it 100% ownership?

In accordance with the new FDI law in UAE - Dubai, what is the (steps/cost/requirements/time frame) to remove the 51% shares local sponsor holder, and make it 100% foreign ownership?

Additional info for accurate answer:

- The foreign owner and the foreign manager are out of the UAE, and the only physical - available person is the PRO person.

- The local sponsor is a company with 4 partners,

So, I wonder if ALL of the partners will be required to attend physically for the procedure of the 100% foreign ownership transfer, or only the PRO and the POA person will be enough?

- The concerned company is an LLC Japanese company for water equipment trading, so it will be under the UAE cabinet positive list, right?
