How are they going to do this? I have a lot of questions... Does SiteGround plan to fix all the mixed media, broken links and other transitional issues that arise from a website HTTP to HTTPS migration? Will they readjust Google Search and Analytics settings to be applied to the HTTPS website?

What if a business wants an OV or EV certificate? Or, a cert from a different CA? Will they have to clean up the Lets Encrypt mess before installing those certs?
