Effect on Portal applications after upgrading ECC 6 EHP4 to EHP 7

Hi Experts,

We are planning to upgrade ECC to ECC 6 EHP7 from EHP4.

Portal version is 7.01 sp7

Could you please suggest whether any portal applications will be effected after EHP upgrading.

We are using ESS/MSS and deployed below business packages.

BP_ERP5ESS 1.41 SP7

BPERP5MSS 1.41 SP7

Kindly advice.

Your response will be appreciated.
