I have an older WordPress site that is going away but I am taking the content from the site and importing it into my new WordPress site.
To do this, I used the WordPress Export tool, located in my dashboard, to create an export file that included all content, including images. The export process created the export file, which I successfully imported into my other WordPress site.
I noticed that if an imported post that resulted from a search or linked in the sidebar had a thumbnail, the URL linked to that thumbnail linked back to the original WordPres site - The site were I created the export file.
How do I fix this?
