Issues migrating media from WordPress.com to ww.wp.xz.cn

I recently migrated my website from WordPress.com to ww.wp.xz.cn using the export/import tool. Similar to the issues that others have expressed on other threads, I had trouble getting all the media to migrate over. After 10 imports I was able to get all the media assets to populate the “Media” folder.

The problem that has come up is that while the assets are listed, photos from 2 years ago and earlier are not showing up. When I look at the wp-content-> uploads folder the photos don’t look to be there.

Is there a way to copy the media files from WordPress.com to the new ww.wp.xz.cn site? I could add the photos using “add media” but with so many assets connected to different galleries and posts it would be very challenging. Any help would be greatly appreciated!
