Migration Issue from PA-500 (HA-Active/passive) to PA-3220 with HA-Active/Passive

[Mohammed_Alalawi]

Hello,

Hi Brothers,

Existing PA-500 (PAN-OS 8.1.17) and New PA-3220 (PAN-OS 8.1.17)

I tried to export the running config from FW (PA-500) as XML format and import it into the new FW (PA-3220)

Shows me a lot of error and warning as there is a lot of discrepancies as following

Is there any recommended solution to solve the issue or should i do it manually?

Hello there.

It appears that the 3220 already has a configuration on it.  Why else would be errors like "tag already in use"
I would ensure that you have NO configuration on 3220 (other than mgmt IP), i.e, a blank config.
If it was me, I would clean up the configuration (expired certificate would be deleted) and other manual steps and then I would try commit.  These errors look very simple to fix.  Five minutes of work at the most.

Good luck.

is the pa500 have a lot configuration?
if no, you can do it manually,

otherwise, you can try using palo alto migration tool (expedition)
