Mubbi Qureshi on "Change Uploads Directory In WP 4.1"

i want to change the default directory of uploads i.e " wp-content/uploads "
i want to set it to " xyz.com/media "

I used UPLOADS constant in wp-config and it is changing the url of the uploaded media but the media is not found on the server or you can say it was not uploaded in that directory...

Kindly tell me how can i change the uploads directory in WP 4.1
