404 Errors after moving blog to /blog

Hi there,

I am a novice and researched this topic, but can’t find link specific to my issue.

I recently updated my website https://www.englandphotography.com. It was pointed at my WP installation. Recently, I updated my website and now link to my old website as the ‘blog’.

My WP was https://www.englandphotography.com
It is now: https://www.englandphotography.com/blog.

Because of this, the links showing in Google search (and other search engines) are still pointed to https://www.englandphotography.com/post name. This creates 404 error.

I need the links in search engines to point to https://www.englandphotography.com/blog/post name.

How do I perform this change? I have resubmitted my URL to Google, about 2 weeks ago, but nothing has changed.

Again, my goal is to point old englandphotography.com blog post links to englandphotography.com/blog.

Any help is greatly appreciated!
