Import of data which includes uploaded files

Import of data which includes uploaded files

I am attempting to switch everything I have in an app from one user name to another (I created it under my personal account, and now the app is being transferred to another account for deployment). A few of my Views have data from uploads (Word documents and image files).

When I import it in any format (XLS, CSV, etc.) the fields which contain links are now populated by links to nothing, and the empty fields for lines which have no uploads have the same.

How do I import all of my data without having to manually copy and paste?
