title: How to tightly link the Images/files stored on the firebase storage to the firestore fields?
body: <p>I'm developing an android app. In that app, I upload the images to the firebase storage and I'll store the image/file URLs to the Firestore document fields.
  My question is if I want to Migrate the database to other project does the URLs are still valid?
  or Tell me how to tightly link the images/files in the firebase storage with its URLs stored on the fields.
  Thanks in advance!</p>
