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,
