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.
| Feature | Upgrade Considerations | Downgrade 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 State | Auto 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 Port | When 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.
