Determine the Upgrade Path to PAN-OS 10.0

Upgrade path planning for PAN-OS 10.0.
When you upgrade from one PAN-OS feature release version to a later feature release, you cannot skip the installation of any feature release versions in the path to your target release. In addition, the recommended upgrade path includes installing the latest maintenance release in each release version before you install the base image for the next feature release version. To minimize downtime for your users, perform upgrades during non-business hours.
For manual upgrades, you must install the base image for a feature release before you upload and install a maintenance release image.
Determine the upgrade path as follows:
  1. Identify which version is currently installed.
    • From Panorama, select
      Panorama
      Managed Devices
      and check the Software Version on the firewalls you plan to upgrade.
    • From the firewall, select
      Device
      Software
      and check which version has a check mark in the Currently Installed column.
  2. Identify the upgrade path:
    Review the known issues and changes to default behavior in the Release Notes and Upgrade/Downgrade Considerations for each release through which you pass as part of your upgrade path.
