Where pve-network-interface-pinning store it's configuration?

Hi...

I am using pve-network-interface-pinning to pin enp1s0, for instance, to eth0, eth1... and so on.
I have 9 nic each server.
But I need to change the hardware and after that, all nic turns back to previously name, like enp1s0, when I use ip a command.
If I try to change it back up eth0, I got this error:
Code:
pve-network-interface-pinning generate --interface  enp7s0  --target-name eth1
This will generate name pinning configuration for the interface 'enp7s0' - continue (y/N)?

target-name already exists as link or pin!

So I need to understand where pve-network-interface-pinning store it's configuration.
Is there anyway to recreate the network interface pinning?

Thanks
 
Sorry!
It was right there in my face! Shame on me...
