How to change security zone name

alirezabtf — Wed, 25 Mar 2026 04:20:00 GMT

Hi,

I created all security zones in Panorama and pushed them to all firewalls. Now I need to change the names of a few security zones.

All firewall policies are based on the current security zone names. Do I need to create new policies with the new security zone names, or is that not required?

Can someone share their experience and advise how to do this?

Best regards,

Hi @alirezabtf ,

In this case you can edit the templates and device groups in Panorama, and then push the changes to the firewalls:

1. Update the names of the security zones under the relevant templates.

2, Update the names of the security zones as referenced in security policy rules under the relevant device groups.

3. Commit to Panorama, and push your changes to the firewalls.

Hi @alirezabtf ,

Technically, you can try to do it that way as @nohash4u describes.

However, I usually advise against the all-at-once approach because of how the firewall handles the cutover. I've seen scenarios where it didn't go right so if this is a production firewall with live users, I would use more of a Side-by-Side method (adding the new zones to the rules first, then swapping, like you mentioned).

Why:
Even if the push is successful, renaming a zone is a disruptive event. When you rename a zone in Panorama and push it, the firewall sees the old ID go away and a new ID created. The result is that active sessions currently flowing through those zones will be dropped and users will have to reconnect.

I believe the process is explained in detail in this post:

Hope this jelps !

Cheers,

Hi @alirezabtf ,

Panorama pushes the config twice to the NGFWs. Once for device groups, and once for templates. This is 2 separate commits on the NGFW. I have always seen the device group pushed 1st. That fails since the zone does not yet exist in the template. If you don't want the change to be disruptive, follow @kiwi's process. If you don't mind a short outage (maintenance window) AND the zone change will not impact Panorama connectivity, try this process:

Create a new zone with the new name. Commit and push.
Delete the new zone and rename the existing zone to the same name. The rename will modify all the policies. Commit and push.

When the device group commit is done, the new zone already name exists, but with no interfaces. When the template commit is done, connectivity is restored.

Thanks,

Tom

PS I have seen the device group commit fail, but then work when the template changes are committed. It appears the DG changes remain in the candidate config. I have always seen zone changes fail completely unless I follow a process similar to the ones above.

@TomYoung @kiwi thanks for clarifying. I was too hasty with my response!
