Zone Rename effects on Panorama and Managed Devices

[egarantiva]

Hello Everyone

I have simple but very important questions about an eventual Zone Renaming in a Template commited and pushed from Panorama to a Managed devices:

1. Changing Zone names inevitably will have an impact on an active sessions ?

2. In PAN-OS 9.0 could I ignore the possibility of taking issues renaming zones when I"ll push them from Panorama?

3. After renaming zones successfully the Historical Logs on Monitor (traffic, threat, url) will update the Zone Fields on the Panorama (Log Collector) and the Managed Devices?  

Thanks for your help

Hello @egarantiva 

The zones are defined in "Templates", and used in "Device Groups". The config push is not a one-shot (if I see it right), meaning panorama is pushing in part after the other.

We had a similar need, followed the following procedure:

- create new zones, but don't assign it to interfaces

- push the templates

- append new zones to policies (you might need to clone NAT policies) -- I did this using a script, making use of the API

- push the device groups

- adjust the interfaces (use the new zones)

- push the templates

- remove the no longer required zones

I would not expect the historic logs will change if you change the zones.

Best Regards
