    Where Can I Use This?What Do I Need?
    • Prisma SD-WAN
    • Prisma SD-WAN license
    • Prisma SD-WAN ION device software version 6.4 or higher
    The following section details the upgrade path to Prisma SD-WAN release 6.4.x. Review the upgrade and downgrade considerations before upgrading to this release.
    Prerequisite—Prior to upgrading branch ION devices to 6.1.X, ensure that all data center ION devices are running ION software version 5.4.x or higher.
    Upgrade Or Downgrade Path
    Use the following paths to upgrade to release 6.3.x, and use the path in reverse to rollback to the version you started from:
    4.7.1 -> 5.0.x -> 5.1.x -> 5.4.x -> 5.6.x -> 6.1.x -> 6.3.x -> 6.4.x
    4.7.1 -> 5.0.x -> 5.2.x -> 5.5.x -> 5.6.x -> 6.1.x -> 6.3.x -> 6.4.x
    5.0.x -> 5.2.x -> 5.5.x -> 5.6.x -> 6.1.x -> 6.3.x -> 6.4.x
    5.1.x -> 5.4.x -> 5.6.x -> 6.1.x -> 6.3.x -> 6.4.x

    Upgrade or Downgrade Considerations in Prisma SD-WAN ION Device Release 6.4.2

    The following table lists the new features that have upgrade or downgrade impact. Make sure you understand all upgrade/downgrade considerations before you upgrade to or downgrade from Prisma SD-WAN release 6.4.2.
    FeatureUpgrade ConsiderationsDowngrade Considerations
    Specific Path Monitoring with Autonomous Digital Experience Management (ADEM)
    Due to a new ADEM feature, synthetic application tests now behave differently on ION devices running 6.4.2 or later.
    If you use ADEM to run synthetic application tests from your ION devices, make sure to check the configuration of those tests before upgrading to 6.4.2. Failure to do so could result in test interruption.
    For all pre-existing application tests running on ION devices that you plan to upgrade to 6.4.2:
    1. In Strata Cloud Manager, select InsightsApplication ExperienceApplication Tests.
    2. Under the Actions column, select the pencil icon to edit the configuration of the application test.
    3. Check the value of Remote Sites Test OptionsApplication Entities.
    4. Ensure that Application Entities matches an application for which you've configured a Prisma SD-WAN path policy rule and that you want to run the application test on that path.
      • If yes, leave as is.
      • If not, set to ANY.
    		None

    Upgrade or Downgrade Considerations in Prisma SD-WAN ION Device Release 6.4.1

    The following table lists the new features that have upgrade or downgrade impact. Make sure you understand all upgrade/downgrade considerations before you upgrade to or downgrade from Prisma SD-WAN release 6.4.1.
    FeatureUpgrade ConsiderationsDowngrade Considerations
    Performance Policy
    If Performance Policy is attached to the site:
    • You can use probes when creating a new performance policy rule, while selecting actions like Create Incidents, Move Flows, FEC, Packet Duplication or Visibility.
    • You can configure the System Rule type and use the new SLA parameters (MOS and UDP TRT) in Performance Policy.
    When downgrading device from 6.4.1 to 6.3.2/6.3.1:
    • You can use existing performance policies, however rules that have new SLA parameters like Probing, MOS, and UDP TRT will not be sent to the device.
    • When creating a new Performance Policy, you cannot apply System Rules.
    Branch Gateway
    If a device is onboarded to a branch gateway site, enable:
    • L3 Direct Private WAN Forwarding
    • L3 LAN Forwarding
    Remove the configurations related to the Branch Gateway such as Service & DC Groups, WAN default route distribution and then downgrade the device.
    Auto Operational StateAuto Operational State is enabled by default for new SVIs and disabled for existing SVIs. After upgrading to version 6.4.1, you need to enable the Auto Operational State, when required.When Auto Operational State is enabled, downgrade to previous releases is not allowed. You can downgrade only after disabling this configuration. Make the necessary deployment changes and then disable the configuration.
    HA over SVI Access PortWhen downgrading to earlier releases, if you have configured an access port, then downgrading will be blocked. Downgrade is allowed only when a trunk member port is present for the HA control SVI.None
    App IDs
    To upgrade devices to version 6.4.1, ensure that all policies contain applications with a version higher than or equal to 6.0.1.
    To downgrade devices from version 6.4.1 to previous versions, ensure that there are no policies containing applications with version 6.4.1 or higher.
