System update

Note

  • In addition to the current system version, Wheel Fudo PAM stores the previous revision, allowing for restoring the system to its previous state. In the event of an unsuccessful system update, Wheel Fudo PAM detects the problem during system restart and restarts itself using the previous system revision.
  • The system update process does not influence the system configuration or the session data stored on Wheel Fudo PAM.
  • The storage usage may temporarily increase during system update.
