File Attachments Export

I am starting new apps from scratch because the existing ones that we have were created by a consultant. I need to be able to export documents, a table from an existing app, into a new app. When I export the documents table it just has the file attachment name instead of the actual file. So then I thought of doing a relationship between the apps but once we have our new ones up and running we will be deleting the old ones. Is there a way to do this where the document stays in my new app once we delete the other? If there is no way around the relationship from the old app, we can always keep it I guess, but only let it show for me.
