Answer: Minimum pre-requisite for Hana is from BI7.3 SP5 or more latest version.
5. how can we implement or Move our BI application to SAP HANA system?
Answer: Once the Oracle DB is replaced with Hana DB over SAP BW/BI server box, the Hana options for BI objects like "Hana optimized cube" etc. will automatically reflected.
