Approach on Migration of ABAP tables in SAP PI 7.1 to SAP PO 7.4

Hi All,

Our project is to migrate the already existing SAP PI 7.1 system to SAP PO 7.4 .

We have to migrate all the existing interfaces to the new version,

For few of the interfaces ,we have used referential Database tables in RFC look UP.

And these tables are maintained in ABAP stack of PI.

Now as SAP PO 7.4 is Java Stack Only,need to find an approach to migrate these tables to PO.

Need your inputs on this.

Thanks in Advance.

Regards,
Sri.
