Hi @Ndexsystems ,
Palo Alto upgrade path is listed here - https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-upgrade/upgrade-pan-os/upgrade-the-firewall-pan...
As mentioned from the link above it is recommended (not acutally mandatory) to upgrade first to the latest maintenance release.
As described here - https://live.paloaltonetworks.com/t5/customer-resources/support-pan-os-software-release-guidance/ta-... 8.1 is End-of-Life, except for some hardware platforms. So if there is no 8.1.25, it means such is not available for your device.
Upgrading from 8.1.24 to 9.0 shouldn't be a problem. If you upgrade from 8.1 to 9.0 has failed I would suggest to troubleshoot the reason. Can you share more details of the failed upgrade and why you decided to roll back to 8.1?
Hi @Ndexsystems ,
The error message should be self-explainatory - every major upgrade requires minimum supported version for dynamic content updates. This is also explained here - https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-upgrade/upgrade-pan-os/pan-os-upgrade-checklist
Verify the minimum content release version.
Minumum content release version is listed in the release notes for each major version - https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-release-notes/pan-os-9-1-release-information/ass...
My personal opinion is to always keep the content version to the latest, so instead of installing the minimum, just update the content update to the latest available.
Does your FW has internet connection? Does it has valid support license? If yes, you can update the content update directly from the firewall.
If no intenet connection, you can download content update from support portal and upload it manually.
