Hi Experts,

I have installed m Net weaver 7.5 ABAP system on HANA base,after this, how to convert to S4HANA, which add-on i need to install in SAP or HANA database.I got below SPS in Net weaver 7.5 ABAP system,

I am not able to see S4CORE component in the list and not able to find the add-on in service marketplace, we have a license for S4HANA also.

Please guide me for this installation.
