Migrating wp site but mantain link beetween images and posts in media section

Hi to all,

i migrated some wp websites in the past. But i had always a problem. Mantain a the links beetween post and images in media section. Now you know when you are in media manager area. For each images there is a column “loaded in” that shows the post where you can find the relative image.
Now i realize that after a migration wp losts (from earlier versions) the links beetween this.
I can see the image on article on front-end there in o èproblem, but in backend area, in media manager i lost the data relative to the column “loaded in”
Is there a solution, or i’m doing something wrong during the migration process?

Thanks very much!
Gabriele
