I plan to travel to Italy and I have a valid C-Visit Schengen visa (issued by German Consulate). however, the Visa is on my old passport which I had to change because all the pages in the passport was full due to visa stamps and entry/exit stamps.

I have been trying to reach the Italian Consulate multiple times (they didn't allow me to enter the premise and no body is answering emails since last 3 days. Also, there is no response at the contact helpline as well).

Really appreciate if someone in this group is aware whether based on the recent immigration rules, is it allowed to enter Italy using the visa on old passport accompanied along with the new passport.
