how to import or migrate nodes between sites of embeded Media content

Hi,

I have two sites. I would like to migrate nodes from one to another.

A simple test: I tried to use copy and past with full-HTML or WYSIWYG editors and it does not show the embeded youtube media in the node body. I noticed that when media module inserted youtube media, it also created (preview) images.

I planed to use Views data export module to export nodes to CSV file and then import by feeds module. According to the tests I did before, I guess it won't work. So how to import or migrate nodes between sites of embeded Media content correctly?

In drupal 6.x (with media) youtube link can be added directly only with the youtube link. I dont know why 7.x change to more complicated way.

Anyone can just give some brief ideas?

Thanks.
