Changing of file url on sync

Hi
I have some pdfs in the posts, but on sync the url of file still references the original websites on which the post was first published i.e if I publish pdf file on abc.com, as abc.com/wp-content/uploads/2022/08/1.pdf on sync I want the url to change to def.com/wp-content/uploads/2022/08/1.pdf, currently it still references original url abc.com/wp-content/uploads/2022/08/1.pdf

How can I achieve this?
