Using 2 Primary Palo410's and 1 Backup 410

[MrJohnallen]

 Morning All,

I have a total of 3 PA410's (each with their own license) that I am using remotely to build a VPN tunnel back to our PA3260 located on our campus. 2 of the 410's are being used in a primary role, each with configs that vary a bit. I'd like to use the 3rd 410 as a backup for each Primary firewall and be able to push a config from one of the primary 410's when needed. The problem is, in order to do that, I'd have to move the licensing as well which complicates and slows down matters. Is there a way I can apply both primary 410 licenses to the single backup 410 to make deployment more flexible? Or is there another way?

Thanks,

John
