Upgrade or Downgrade Considerations in Prisma SD-WAN ION Device Release 6.5.1

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 6.5.1.
FeatureUpgrade ConsiderationsDowngrade Considerations
Secure Fabric Prisma SD-WAN Tunnels for DC to DC
In case you have a hybrid topology, where you already have standard VPNs, configure a prefix list for the first data center which explicitly denies the prefixes coming from the second data center on the Standard VPN path. Otherwise, traffic will be looped back to the first DC device.
After upgrading your device to software version 6.5.1, all the existing BGP peers will be set to Local. This is to have better control over the learned prefixes. If you want to distribute the learned prefixes, you will need to change the setting to Global.
Support for GCM EncryptionNone
If you have configured the GCM algorithm for ION devices running software version 6.5.1, ensure that you select at least one CBC algorithm before downgrading the device.
