Certificate management when replacing a controller

When replacing JACE controller in the field, you may reuse backups of the User Key Store and User Trust Store from the old controller. If no station backup is available, you must generate a new server certificate and sign it or get it signed.

You are on site. Remotely importing a security backup into JACE controller is not recommended because you should not restore the User Key Store and User Trust Store while the station is connected to the Internet.
  1. Make sure that the JACE controller is not on the Internet.
  2. Reboot the controller and restore the station.
  3. Either restore from the station backup, or import the stores from a previously exported file.
