Migration FROM PA-850 to PA-3220

L4 Transporter


Good afternoon, what is the best migration option from a Palo Alto PA-850 to a PA-3220.


Thinking for example to be able to keep the self-signed certificates in the PA-850, used for Global Protect.


Based on your expertix and experience, what is the best way to approach this migration.

I remain attentive, thank you very much.

Best regards

Hi @Metgatz ,


This is what I do:

  1. Configure the licenses, software, and dynamic updates to match on the new firewall.
  2. Export and import the certificates.
  3. Export and import the config.

That's it!


I have never played with exporting and importing the device state.  That may include the certificates as well.
