Sarah Gooding, WP Tavern:
The next major release of WordPress will make it much easier for users to migrate their sites from HTTP to HTTPS. It introduces new capabilities to detect if the user’s hosting environment has support for HTTPS and provides a one-click update process, handling mixed content rewrites where possible.
Moving from HTTP to HTTPS is good for everyone, so this upcoming feature is great. I’m wondering how this will work in the backend though. If it’s a dynamic rewrite process, there may be some performance penalty. At the end of the day, running a search and replace on the WordPress database is still the best way to move from HTTP to HTTPS. Regardless, this new feature is still great for users who are not able to do it the proper way.
