Changes to Default Behavior in Prisma SD-WAN ION Device Release
5.3.1
Keep the following upgrade and downgrade
considerations in mind when upgrading or downgrading your devices
to and from Release 5.3.1.
To upgrade to Release 5.3.1, you must upgrade first to
Release 5.0.1 or Release 5.0.3.
Migration or downgrade to a release is not allowed, if that
specific release does not support GRE Third Party Tunnels and the
ION device has a GRE Tunnel configured.
There will be no maintenance releases for Release 5.3.x.
It is recommended that customers who plan to upgrade to Release
5.4.x, when Release 5.4.x becomes available, take advantage of Release
5.3.1 features now.
