Is it safe to move my modules
- From sites/all/modules/
- To sites/all/modules/contrib and sites/all/modules/custom
on a production site?
That is, does Drupal automatically detect that the module is still there, but in a new path?

If you move a module Drupal will see that the old one is broken, and a new one exists. It will not assume the two are the same thing - simply moved.
Drupal stores the file location in the system table, the info will be rebuilt when you clear the module cache, so if you move the stuff and clear the cache afterwards you should be fine.
