Downgrade Firewall from 10.0.0 to 9.1.1

L2 Linker

Greeting Team!

I noticed some problems with a downgrade in my internal lab. So, some information: I want to downgrade from 10.1.7 to 9.1.1 (i need it for the experiment).

1st step i downgrade from 10.1.7 to 10.0.0, everything fine. But, when I want to downgrade from 10.0.0 to 9.1.1 I faced an error with: Upstream NAT not supported on 9.1.1, please delete it. (i can show it if needed).

I check the information about that, I find some. Like workaround advice to 1st have 10.0.3 or 10.0.4 PAN-OS, then delete upstream NAT from each interface. I try it, but, nothing, cli logs I can show too if needed.

 

Does somebody face that problem?

 

Thank you and have a good day!

if you're doing this for an experiment on 9.1, you could factory reset your device so you don't have to battle artefacts

Dear Reaper, thank you for your response.

I need that experiment, cause soon I will do a downgrade on my working firewall. I can`t factory reset my firewall.

 

Best Regards.

Hello,

Is there a reason you need to downgrade? Is there a bug you are facing? Also which model of Palo Alto are you attempting this on?

Hi Dear Otakar,

 

Is there a reason you need to downgrade? - I need to be sure, that workaround works, and then apply it on the working firewall

Is there a bug you are facing? - I don't know actually, maybe its a bug, but I can't find information about it.

Also which model of Palo Alto are you attempting this on? - I go WM-50
