I would highly suggest you engage with your account/partner manager if you are unsure of how to do this to ensure the implementation goes smoothly with the customer, I would not recommend you attempt this if you are not familiar with this configuration.
I really cannot offer further information, as the Community is not really the place to get such detailed information, this would normally be handled as a services engagement, as there needs to be quite a bit of user case review etc. in order to ensure things are properly architected.
