Importing Images that are in Post Content

Hello!

I have some Blog Posts to import from an Old Blog to a New Blog. I managed to correctly import all their data and Contents. Featured Images were also correctly imported as Attachments and are now in my New Blog Media Library.

But I noticed that the Content of these Posts had images. The images are in the Old Blog Media Library. My imported Posts in the New Blog are showing the images in Content but they are all in the Old Blog URL wich will be deactivated. So I need to import these images in my New Blog Media Library.

Should the Importer had done this automaticly or should I activate some option to do that? Perhaps I missed something?

I read the docs in https://www.importwp.com/docs/import-wordpress-posts-from-any-xml-or-csv-file/ but it was not clear to me what to do with the images that are in Content of the Post. Are they treated as Attachments? I wouldn’t know how to select them as their URL are in the Content of the Post.

Thank you.
