Upgrade path from PANOS 9.0.17-h5 to 10.1.13-h1

Hi Experts, 

I'm going to upgrade from PANOS 9.0.17-h5 to 10.1.13-h1. Could you please advise me the download and install path. Additionally, Tell me how many reboots. It would require reaching out to 10.1.13-h1. 

Moreover, can you please help in order to prepare a plan, we need to determine how much time to request for the change window and the expected duration for a reboot cycle.

Hello @deepakkumar29 ,

The upgrade path would be as follows:

• Download and install the latest preferred PAN-OS 9.1 maintenance release and reboot.
• Download PAN-OS 10.0.0.
• Download and install the latest preferred PAN-OS 10.0 maintenance release and reboot.
• Proceed to Upgrade the Firewall to PAN-OS 10.1.

However I would recommend you take a look at the End of Life for PANOS versions to see when 10.1 will go EOL and compare with 10.2 or even 11.1.  This will give you an idea of the updated PANOS versions available to help reduce how many times you will need to go through an entire upgrade path in the next 1-2 years or so.  

It can be difficult to determine how long a change window should last so I would recommend perhaps testing the upgrade in a lab environment to get a potential idea of how long the process can take. 

Thanks,
