Manage image problems after migration from wordpress.com to self-hosted blog

Hi to all,

how are you? It’s a very long time i don’t post on wordpress forum.
I have some question and some suggestions for all about the migration from a blog on wordpress.com to a self-hosted wp site.

I’m migrating a blog with very large number of images (2500!).
I create new istance of wp on my host, i installed all plugins that i need (without installing jetpack) and then i create a export file from wordpress.com blog.

I imported it to my blog (i create first developer instance and not directly on production). I checked all options and also check donwload all images and then import on new site.

Onb my hosting aruba perhaps i think i have some problems and i had to click on import many times on the same files to upload all images and posts…

All goes ok!

Posts are perferct and images are displayed on media manager.
But there some problems after migration.

Images are now unatacched (2300 on 2500) with posts. And naturally all refers of links and tags fro my old blog are different.

I resolve the problems of the wrong links with a plugin “Real time find and replace”. I’ve searched for wrong path and i correct it perfect!

For images, i discovered too late this plugin “https://www.ads-software.com/plugins/media-tools/screenshots/” that import images from posts.

All images and galleries on my site are ok and the paths are correcct but i don’t know if there are some problems without reassociate all images with posts.
Exist a tool that scan my posts and automatically re-associate all my images?

Or there are some filter fro media manager that help my self?

Thanks for all!
Gabriele
