You basically need to delete them from the autopark node and move them to the new node, however, I am assuming you want to maintain the config from the autopark node to the new node? If so, you can cd into the autopark node, do a 'show config committed', copy and paste that output, cd into the new node, paste in that config, then delete the controller out of autopark node and move it into the new node.
Yes it's a pain, yes we are working on a feature for AOS 8.2 or 8.3 to support an easier move solution. :)
