How to change the mount point on an already installed Linux system?

[RizzoHou]

I previously installed an Ubuntu system using Linux Deploy, and the mount point was set to /storage/emulated/0/Download without specifying a location. It automatically mounts within the Ubuntu system at /storage/emulated/0/Download. Now, I want to remove the existing mount and add a new one with the mount point as /storage and the location as /media/ (I'm not sure if the wording is correct, but what I want is for the files inside /media/storage to be the same as those in the original /storage directory). Is there a way to achieve this without reinstalling the system?
