I see, thanks!

That binding was defined "upstream" in outline.el

,-------------------------------------------------------
| (defvar outline-mode-prefix-map
|   (let ((map (make-sparse-keymap)))
|     (define-key map "\C-v" 'outline-move-subtree-down)
`-------------------------------------------------------

so I could not find it in my own sources, and it was still around
although I defined alternative bindings myself.

PS
and 

,------------------
| C-h k C-c C-v RET
`------------------

returned "undefined" because I had actually a different prefix than "C-c"
defined in my init.el ...
