I am migrating domains and redesigning the site at the same time. My large image sizes are different than they were before. When I imported the old posts, I had it download all the images as well. My problem is that the images that were inserted with the old file size name. Is there a way to replace all of the images with the correct new image sizes? I just want it to use the default ‘large’ size, even though it is different than the original site.
In post html:

Actual image sizes:

Use plugin Regenerate Thumbnails to resize thumbnails.
Edit:
Try use filter “the_content” to convert in post content.
Filter “the_excerpt” if need convert excerpt too.
