Copy Controller Database

  %userprofile% \Ubiquiti UniFi\data
  1.) Stop the Controller.
  2.) Make sure java and mongod are not running (on Windows Mongod is rather persistent, so it's best to perform the following steps in Safe Mode)
  3.) Copy the new keystore (found in new /data directory) file to the old backup /data directory, overwriting the old one.
  4.) Delete the new /data directory.
  5.) Copy the old /data directory to the new UniFi installation.
  6.) Restart the controller
