Determine the Upgrade Path to PAN-OS 10.1

Upgrade path planning for PAN-OS 10.1.
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 download the base image for the next feature release version. To minimize downtime for your users, perform upgrades during non-business hours.
For manual upgrades, Palo Alto Networks recommends installing and upgrading from the latest maintenance release for each PAN-OS release along your upgrade path. Do not install the PAN-OS base image for a feature release unless it is the target release you want to upgrade to.
Determine the upgrade path as follows:
  1. Identify which version is currently installed.
    • From Panorama, select
      Managed Devices
      and check the Software Version on the firewalls you plan to upgrade.
    • From the firewall, select
      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.
