PI 7.0 dual stack to PO 7.5 Single stack ESR objects

Hi Folks,

We are upgrading from PI 7.0 to 7.5 and aware of directory cockpit but

1. How do we migrate ESR objects ?

2. The name changes for message to service interface etc. would be taken care by file transport or not ?

3. Interface mapping to operation mapping ?

4. From Basis stand point is there a direct path or we need to bring it to 7.31 first and then to 7.5

Please suggest.

Regards,

Sachin Dhingra
