Hello,
Please read the WWI Cookbook (search here or SAP Notes) to get a full understanding of the WWI setup.
You should in my opinion not use SV001 and SV003 in your production environment.
These are for DEV and QA - and if you want to test a new WWI Version in DEV or QA you would impact PROD immediately.
You need new WWI Servers/Services on the windows side!
You can use CGSADM to install additional WWI Services on the one WWI Generation Server linked to PROD (SV002). You need new RFC for these additional WWI Services. Please see the cookbook for details.
Regards
Mark
