Is SAP ERP 2005 SR2 (SAP NetWeaver 7.0 SR2) supports windows server 2008 R2?

Hi All,

Is SAP ERP 2005 SR2 (SAP NetWeaver 7.0 SR2) supports windows server 2008 R2? Currently we are running SAP ERP 2005 SR2 with windows server 2005. We are planning for OS migration windows server 2005 to windows server 2008 R2. I got the reply from SAP they will not support it. But i have already installed and ready for Development and quality server, now I need to work for Production server. which type of issue will come with this landscape. Can we go ahead or i need to stop this activity. Our future plan is to upgrade SAP NetWeaver 7.0 SR2 to ECC EHP7.
