Netezza BI 4.0 IDT 32 Bit Multi Source Universe

Hi

We are about to go ahead and deploy BI 4.0 sp6 on our environments with Netezza connectivity. I happen to stumble upon a PAM document (.xlsx) by SAP detailing supported/unsupported features of BI4.0 with Netezza. Now it shows that multi-source universes are not supported on BI4.0 Netezza 32bit driver, where as Netezza BI 4.0 supports Multi source universes on 64 bit drivers.

Our developers will have access to 32 bit client tools including IDT using which they would have created multi source universes.  Does Netezza 6.0 supports MSU on 32 bit clients if not is there an alternative to achieve the above?

Thanks

Samir
