Changing the Base Frequency in PSSE

I am simulating a system where Two different networks having 50 HZ and 60 Hz frequency which are connected via Back to Back HVDC. Since PSSE can take only One frequency at a Time. So I am converting the model of 60 Hz to 50 Hz.

I need to know which parameters would required to be changed in the steady state Load Flow Case as well as in Dynamic.? For Dynamic, the inertia constant of Machines and Motors will require an update. What is the relation of frequency with the inertia constant.? Thanks in advance.
