I want to migrate the existing CIG project which is in status "In production" and connect it to a different System. Does anyone have any experience with this? I have both test and production connections within the same CIG project so deleting it is not an option since production has to keep running.
While if I create a new project and use it to connect one test Ariba system to the new S4 Hana system, question is what to expect of the existing test and prod connection from an old project.
Thank you in advnace,
As I mentioned earlier, you can have as many systems or projects as you need, and they will not impact each other since each will have a unique SystemID and URL for connection.
For this new project, you may assign a dummy SystemID in the test environment and use the real one for production. If you're utilizing the SAP Business Network, the SystemID is included within the cXML data that is sent to CIG. Consequently, CIG will route the document to the appropriate ERP.
This arrangement is similar to having multiple systems in a test environment—like sandbox, development, QA, and UAT; all within different projects, with CIG routing the documents back to them.
I believe you cannot change the SystemID after you move the project to production.
You can try to open a ticket to have that changed for you, or you could create a new project and deploy to production.
Remember that CIG is a middleware and should accept multiple SystemIDs; you have also to configure this new system in the network as well, if you are using other Ariba apps it is required to use custom routing instead.
