Replace firewall order

ce1028 — Wed, 06 Oct 2021 15:32:18 GMT

I have a question about upgrading a firewall to new model. I've done it in the past but always seem to forget the order.

I have a firewall that is managed by Panorama, with some local policies also. I have downloaded the device state from the existing firewall. I have also added the serial number of new firewall to Panorama but I have not configured the blank firewall with the Panorama IP address yet.

Do I have to connect the blank firewall to Panorama first, wait for it to show connected in Panorama, push to new firewall and then restore the device state to new firewall? I feel like the order of operations may be wrong here

@ce1028,

You would pull the device state for the old firewall and then replace the device on Panorama and commit the change. On the firewall you are setting up you would import the device state that you grabbed and commit that configuration. Once that's done you just need to sync the firewall and Panorama.

Thanks @BPry , so the below is accurate? Note: Old device will remain online until cutover of new device

1) export device state of existing firewall

2) add Panorama IP address on new firewall, commit

3) add new firewall serial to Panorama, add new device to proper device group/template, commit to panorama

4) import device state on new firewall, commit

5) push from Panorama to new device

@ce1028,

No, you can remove step 2 from your list entirely. You don't need to attach the device to Panorama before replacing the old device SN with the new device SN and loading the device state on the new firewall.

Thanks @BPry but if I replace the device serial, then the existing firewall will no longer be managed by Panorama. The plan is always to pre-configure the new firewalls and then cutover a different day. I typically would replace the serial number only on a faulty device

Guess I'm missing something here
