Integration between HCM HANA (On Premise) and SuccessFactors using PI

Good Day Experts,

Actually we are working with a company that has SAP HCM on Sybase integrated with SuccessFactors using PI, the last month this company tells us that they will be migrating Sybase to HANA by the end 2015.

I was wondering if it is possible to integrate HCM HANA (On Premise) and SuccessFactors using PI?

and finally what are the implications with this?, do we need to re-map fields?, re-install the addon?

Thanks so much for answers.

Best Regards,
