I am about to make a site move to https - my developers are doing this using a server-level rewriter and have said this means that redirects will be done automatically so no 301s are required from our old HTTP versions.
Please could you advise if this is correct advice?
This is a well-established site with quite a lot of backlinks and we obviously do not want to risk a big ranking drop.
<?php header("HTTP/1.1 301 Moved Permanently"); ?>and you should now add 4 website variations to Google Console. – Simon Hayter Dec 16 '17 at 16:11
