Hello Geetanshi,
Please find below my responses -
1) In SLD for Technical System and Business systems of type ABAP we will use the same RZ70 from ECC approach to Change the Business system name during imports in new SAP PO system. I think same approach will be used here as well?
I meant, if you change the Business system name, then the existing proxy interfaces in PI 7.1 will be affected. Because the proxy setup will be same for both the systems. Hence suggested to use the same Business system name of ECC system.
2) As we are migrating from SAP PI 7.1 to SAP PO 7.4 we don't need to change the code for Java mappings and Custom modules. Just need to re-deploy? Please clarify this.
AFAIK, there is no code change required, but recompilation is required as the java versions will be different.
3) For converting ccBPM into BPM Where I will get the Integration pattern for standard BPM as mentioned by Nitin. Please clarify.
Here you will find the example patterns -
