Process to integrate Ariba over existing Ariba CIG for ECC to S4HANA Conversion?

[shashank_naik]

There is an existing connection from Ariba to ECC over Ariba CIG. There is a planned ECC to S4HANA conversion. That means the backend system is changing.

The requirement is to continue to use Ariba CIG for Ariba integration.

However, what could be the process/steps on Ariba and Ariba CIG side to be followed to setup / repoint the connection to S4HANA?

almost the same steps when you configured to connect CIG to ECC

Best Approach is to connect one Child Realm with ECC and another Child Realm with S4HANA. Rest CIG Configuration is same.
