Commencement Ceremony

So I am graduating this semester with a masters in Astronautical engineering and there are two ceremonies I can attend. The main ceremony where it seems like everyone will be able to attend then the Viterbi which is program specific. I originally planned on attending just the Viterbi commencement but I wanted to know if I should also attend the main. Like is there even a point to it? My understanding is that I won’t be walking the stage in the main but at the Viterbi commencement. Please correct me if I am wrong just trying to understand the traditions! Currently a DEN student if that matters. Thank you!
