Upgrade SAP NW to EhP2 but not SAP APPL 600

Hi SDN,

I'm searching for some documentation to know if it's possible to upgrade only the Basis NW component of an SAP ERP 6.0 installation without upgrading ERP Components to any EhPx. I didn't found any documentation telling me that it's possible or it's not possible.

The final system should be something like SAP BASIS 7.02 with SAP APPL 600, taking into account the SP equivalence.

The goal is to migrate the ERP 6.0 system to SYBASE.

Do you know about any documentation with this kind of information?

Thanks in advance,

Pedro
