Travel to Romania with valid Schengen visa in my old passport

I am an Omani national. Recently I renewed my passport because its expiry was in less than 6 months. I have a valid Schengen visa in my old passport for another 3 months. Now I want to travel to Romania for a week. Is it possible to take my two passports and use the Schengen visa in my cancelled/old passport for entry into Romania?
