Upgrade ION Device Software

Learn more about the upgrade ION device software in Prisma SD-WAN.
You can schedule ION device software downloads and upgrades in a staged manner, allowing multiple attempts within a specific period of time while eliminating interruption to the network.
Software scheduling is not available for pre-release 5.1.1 devices. Upgrade your device to version 5.1.1 to take advantage of scheduling downloads and upgrades.
Schedule downloads and upgrades to start at a designated time. If you do not provide download and upgrade time, the upgrade immediately follows the download. If you provide only the download time, the upgrade does not immediately follow the download, and needs to be scheduled. The download interval and the upgrade interval serves as a limit until download or upgrade attempts are performed respectively.
If you specify interface IDs, the device uses the specified interface to perform the software download. If you do not specify the interface, the ION device uses the controller interface or any interface that is marked as use for internet. If you specify multiple interfaces, then any available interface provided in the list is used in random order. No interfaces outside of the manually-specified list are used.
You can schedule upgrades and downgrades as follows:
  • Upgrade without Max Upgrade Time
    —The ION device automatically performs the download and the upgrade sequentially at the scheduled time. If the ION device experiences an upgrade failure, it retries the download or upgrade three times before it indicates a failure.
  • Upgrade with Max Upgrade Time
    —The ION device starts the download and the upgrade sequentially at the scheduled time. Max Upgrade Time serves as an upper limit until which the download or upgrade is tried by the ION device. If the ION device experiences an upgrade failure, it retries the download or upgrade three times before it indicates a failure. The default Max Upgrade Time is 30 minutes.
  • Download without Max Download Time
    —The ION device performs the download at the scheduled time. If the ION device experiences a download failure, the device retries the download or upgrade three time before it indicates a failure. If there is a download failure, the device does not perform a software upgrade.
  • Download with Max Download Time
