What happens to NAS sources when you move to a new network?

Hi, I have an Asus Chromebox running LibreELEC with Kodi 16.1. I’m using a NAS storage device for my files.

Suppose I create sources (with SMB links) and add folders from my NAS storage and then update my library.

Will Kodi still be able to find my files if I bring my setup to a friend’s house and connect it to his router?

Will I have to update the original source that I created or will Kodi be able to find everything again?

If it can’t find my sources and have to recreate my sources and update the library again, will this create duplicate thumbnail files? How do we avoid creating duplicate thumbnails?

Thank you!! LaughBig Grin
