Is both HTTP and HTTPS should be verified in Webmaster Tools

Question

I am struggling to get solution of issue which i am currently facing. Lately, we have upgraded our website with SSL and redirected the entire site from http to https with all urls. The site is currently added to Google Webmaster Tools as www.pnrstatusbuzz.in and all the pages are indexed without using SSL. Do I just submit a updated sitemap which has the HTTPS URLs or Do I add a new site as https://www.pnrstatusbuzz.in and submit the sitemap with HTTPS urls?
