Thank you so much for your reply, this made a lot of sense.
So here is where I stand right now, and the dilemma I have,
I brought up the new 5220's, and I made the changes to the interface configurations, and cloned the template, and made a new template stack, and was able to get all of the template items pushed to the new 5220 HA pair through Panorama.
But when it comes to the device group, we have roughly 500 NAT rules, a lot of which reference the interface in the translation; and since the interface is not the same it errors out when pushing to the devices.
So my thought was to create a new device group since I can't use the old for the above reason. But I can't find any way to clone the Device Group, and I dont want to re-create 500+ ACLs and 500+ NAT rules.
I looked it up and saw the partial load configuration command line, but I keep getting invalid syntax, and I tried creating a new Device Group and cloning just the NAT rules to it but that throws an error as well when I try to clone them to the new device group.
Trying to find a way to get this device group cloned, so I can then edit the NAT translations to reflect the new interface mappings.
