Hi,
So this means both the system are different SID and are connected to each other as the postal is used to get the data from the backend.
So you can just do the abap copy but you need to take case of the following things.
Where is the ume of the portal system . is it abap. if yes then you will have to change the users and settings.
Do you have JCO and system landscape defined in the portal to point the backend if yes then you will have to change them.
If SSO is there between the portal and the abap system you will have to reconfigure it.
If you are refreshing the Abap system you will have to do post system copy for abap plus also have to configure the portal so that all the functionality works.
Thanks
