Integrate HANA Source System to BW on HANA

Hi All

I have a more architectural level question, found a lot of answers on the web but really what I am looking for is an expert opinion (probably someone who has done this before)

We will soon have an upgraded brand new shiny BW on HANA 7.5 (NOT BW/4HANA) - My requirement is to do ETL from another Native HANA system. I have BODS in my eco system which I can probably use, but my ask is, since they are both HANA 2.0 databases, is there a better option out there, I was looking at Smart Data Integration but I am not sure if this is the use case for that ? Any thoughts/opinions will be highly apprecieated.

Thanks

Sameer
