How to upload re-issued passport info while you’re on ip2 stage?

hi I submitted my EE profile with my old passport and currently under ip2 ( medical passed , biometrics given) stage. Now I re-issued my passport since it was expiring soon. How am I going to upload the new passport info to the CIC?

What will be my visa application center in web form . I applied from US. Also how can I attach copy of my new passport pdf on webform? Or should I just mention my new passport no as text?
