On second though, you may want to test the following:

  (defun org-update-link-syntax ()
    "Update syntax for links in current buffer."
    (org-with-point-at 1
      (let ((case-fold-search t))
        (while (re-search-forward "\\[\\[[^]]*?%\\(?:2[05]\\|5[BD]\\)" nil t)
          (let ((object (save-match-data (org-element-context))))
            (when (and (eq 'link (org-element-type object))
                       (= (match-beginning 0)
                          (org-element-property :begin object)))
              (goto-char (org-element-property :end object))
              (let* ((uri-start (+ 2 (match-beginning 0)))
                     (uri-end (save-excursion
                                (goto-char uri-start)
                                (re-search-forward "\\][][]" nil t)
                                (match-beginning 0)))
                     (uri (buffer-substring-no-properties uri-start uri-end))
                     (start 0))
                (when (catch :obsolete
                        (while (string-match "%\\(..\\)?" uri start)
                          (setq start (match-end 0))
                          (unless (member (match-string 1 uri)
                                          '("25" "5B" "5D" "20"))
                            (throw :obsolete nil)))
                        (y-or-n-p
                         (format "Possibly obsolete URI syntax: %S.  Update?"
                                 uri)))
                  (setf (buffer-substring uri-start uri-end)
                        (org-link-escape (org-link-decode uri)))))))))))
