B.3 Restoring a controller team
NOTE: Before running this script, re-install the controller. Otherwise an Error 404 condition results
and the controller is not restored. See “Restoring a controller from a backup ” (page 95).
Because the scripts in this appendix cross page boundaries, be careful to avoid including the page
number when copying a script. Copying a script one page at a time can prevent inclusion of page
numbers.
