Keeping correct paths after migration

Hello,

I have a decent sized site I will be migrating from my development server over to the server where it will reside. At the moment the path to the PDF files notes the URL of my development server.

What I would like to know is if this will change once the site is moved over and the correct domain is inserted in the ‘Settings’?

The last thing I want to do is to go through 90+ file links and edit those to reflect the correct path.

Thank you in advance.
