We have a client that wants to convert their WordPress site to ssl. The certificate is already installed and is working as we tested changing the http to https in a browser and are shown the certificate and error messages that certain hard coded links need to be modified.
When we modified our company WordPress site, all of the redirects were in place without us having to do anything. Initially all pages showed HTTP/1.1 301 Moved Permanently (to https) and about a week later are all showing HTTP/1.1 200 without having to do any redirects ourself.
My question is this, do the redirections happen automatically on the server side, the WordPress side or somewhere else? I understand there will be ranking changes initially, but i don't want to leave out a step that may harm the client's rankings.
