How to convert Std DSO into Advance DSO in SAP BW

Hi Experts,

Please suggest if it is possible to convert to Standard DSO into HANA Optimized DSO later:

1. If no is it going to be possible in upcoming releases.

2. If yes what are steps involved in doing so and effort considering development and taking into consideration the Data that the Std DSO might be holding at that point of time.

Thanks
