Always, I run the portal sync process for EMPLOYEE portal in CS. There have been changes on permission lists associated with HC_REGISTRY. I ran it in the test for this portal (HC_REGISTRY). Does anyone know if this will do any harm?
Portal security synch doesnt cause any harm. When you maigrate permission lists,roles,userprofiles from a different environment to your current one, its necessary to run Portal sec synch so that all the security tables are in synch.
Additionally you may chose to delete the invalid entries
