System copy from Dual Stack (SEM-BCS) to single stack (SEM-BCS)

I have an old source BCS-SEM system (SAP NW 7.1 SEM-BW 604) which is on a dual stack. As part of moving the systems to a new cloud platform we have build the target BCS-SEM system (SAP NW 7.1 SEM-BW 604) as single stacks since SAP does not provide option to install dual stacks.

The platform is Windows /SQL 2008 running on VMWare.  Is there a way I can either move the dual stack database to single stack using SQL tools or somehow build the target environment as dual stack by some copy /clone method without installing the SAP single stacks.
