SAP Adapter 10.7 Issue Routing Listener

Hi Team,

We are migrating 9.9 to 10.7.

We have migrated some SAP Adapter notifications from 9.9 to 10.7

  1. We have multiple adapter notifications running on same listener.

    Listener is enabled in both old and new servers as there is dependency on both servers.

    We have disabled the migrated listener notifications in Old server.

But issue is when SAP team is trigger IDOCs sometimes it is going to New server and sometimes to old server.

Is there any issue with the routing listener.

Could please anyone help me out. As PROD is next week
