This article will be archived in March 2022. Refer to Upgrading PAN-OS documentation for the detailed upgrade procedure.
First lets understand the PAN-OS versions naming:
| Release Type | What it offers | How to identify |
| Major | Features & fixes | 8.0.0 |
| Minor | Features & fixes | 8.1.0 |
| Maintenance | Fixes | 8.1.1 |
We will address PAN-OS upgrade from 8.0.X to 9.0.X and also the same from 8.1.X to 9.0.X where X is maintenance release version that is is not 0.
Procedure
From PAN-OS 8.0.X to 9.0.N :
- Prerequisite : Firewall is running 8.0.0 or 8.0.X where X is maintenance release version that is is not 0.
1- Download 8.1.0 (To go from Major/Minor release to another Major/Minor release (Ex. from 8.0.X to 8.1.X) you need the firewall to already have Major release base image which has Y.Z.X where X is 0.)
2- Download and install 8.1.n where n is the latest Maintenance release version available for example at the day 5th of July 2019 the latest Maintenance release was 8.1.9.
- Note: Its best practice to go to the latest Maintenance release as explained in step 2 but it can work fine by downloading and installing 8.1.0 and skipping step 2.
4- Download 9.0.0 as we explained in step 1
5- Download 9.0.N where N is the targeted maintenance release version.
From PAN-OS 8.1.X to 9.0.N :
- Prerequisite : Firewall is running 8.1.0 or 8.1.X where X is maintenance release version that is is not 0.
2- Download 9.0.N where N is the targeted maintenance release version.
