moving wordpress to http2 (via https)

I just moved my wordpress site to http2 (via https). Some advice on steps to moving your site ;

• Run it behind nginx + lets encrypt – offload ssl certs and get http2 performance
• Setup nginx default to redirect all http -> https
• update your WordPress site to correct URL (via admin / settings / general)  i.e. https://sigtar.com
• Run WP plug-in to change all media / links to new https links. Else you get mixed secuirty (some http, some https)
