SAP Security upgrade and RAR update in GRC 5.3

Hi Experts,

I am new to SAP Security upgrade and please excuse me if its a basic question.

We are planning to upgrade from EHP 4 to EHP 6 in ECC system and we could see that around 900 authorization objects are getting modified/added to the system.

If these many new object gets added to the ECC system, how do we update the standard rule sets(also Functions and Risk IDs) in RAR within GRC 5.3?

Is there any note which we need to update the SAP GRC 5.3? or do we need to manually update the standard rule sets within GRC and how do we do??

Please assist? Currently we are in support pack 20 for GRC 5.3.

Regards

Julius
