It's not possible with plain mv, unless you modify the source to add that capability, but you can do it in two steps with rsync and rm. The option to look for in the rsync manual page is --progress. Maybe also --partial.

Code:

man rsync

Then if the transfer is successful, delete the old file.

If the two files are always going to be on the same partition then ln could be used to make the change instantaneous.

It makes links between files. A hard link just creates an additional name pointing at the same data. The data won't disappear until the last hardlink is removed. So if you create a new name in another directory, you then delete the old one without losing the data or even having to move it. However, hard links only work within the same partition and not across file systems.

Soft links won't work in this case.
