Copying data from OLD BW to NEW BW server

Hi guys,

Just want to ask how can I transfer the data of DSO from our OLD BW (BW 7.0) system to our NEW BW (BW on HANA) server?

I tried openhub and APD but I can't find the logic or way how will the OLD BW system know its target DSO in the NEW BW server..Is it possible using OPENHUB or APD? Or the only way is the GENERATE EXPORT DATASOURCE option?

Thank you..
