Upgrade Palo Alto

[khalil.extern11]

Hello,

I have Palo Alto with current version 10.2.7-h3 that is HA and would like to upgrade to version 11.1.4.h18.
I am looking for an official Palo Alto link that describes the required upgrade paths (for example: from 10.2 to 11.0, then from 11.1 to 11.1.4, etc.).
I would like to share this link with my manager. I found one link, but it does not mention the intermediate upgrade paths required.

Thank you in advance for your help.

You can upgrade directly, there is no intermediate upgrade path if you are upgrading from any 10.2 release to 11.1. You can always find the upgrade path through the PAN-OS upgrade guide that is published for your target major version; in your case that is located HERE and can be confirmed on page 123

Thank you for your reply.
If I understood correctly, with my current image 10.2.7-h3, I can go directly to 11.1.4-h18,
or should I first upgrade from 10.2.7-h3 → 11.1.0, and then from 11.1.0 → 11.1.4-h18

@khalil.extern11,

Correct. You'll want to verify that you meet the requirements to run 11.1. You can verify the checklist in the document that I shared earlier (page 106) to make sure that you've reviewed all of the upgrade considerations. Then review the release notes to verify that everything in your environment meets the minimum compatible versions HERE and ensure that you have the minimum content version of 8761 installed.
