If you do not have a SOAP license, you will have to work offline, and manually upload your workflows to the server.
Nicholas, You need to have a SOAP license in order to connect to the TS 6.7.1. If you dont have the license then you need to use the IW WFM in offline mode. Once the models are created then you will have to import the Model [.ipm file] within the iwadmin/main/workflowModels/WORKAREA/iw-wa/Models folder. You will also have to rename and import the corrosponding ****_config.xml and then submit all the files to staging.The best way to have a SOAP license to avoid all the manual hassles while publishing the Models.
