Need correct portal version for backend ECC6 EHP7

Hi Team,

We are working on a SAP HCM project where the backend is being upgraded from ECC6 EHP4 to EHP7. Current SAP NW Portal version is 7.0.

Please let me know the right SAP Portal version to be upgraded to as per the backend version EHP7 or can we still use the existing NW7.0 for all ESS/MSS functionlaties.

The project is majorly HCM functionalities like Performance management, Learning Management, Succession management and Recruitment.

regards

Bharat
