SAP BW 7.4 ODQ and RSA7

Hi All,

We are planning to run BW 7.4 on HANA and BW 3.5(older content data sources) systems paralally with 1 ECC.

In RSA5 we have delivered version ODQ capable data source (2lis_11_vaitm), If i activate delivered content old data sources to BW 3.5 system will work? (there is no rollback if i activate the data source from content)

If it works delta queue's are maintained in RSA7 and ODQMON? any thoughts please share ..

Thanks.
