Palworld Server

I'm hosting a palworld server on a mini pc with Ubuntu server installed on it.

I want to create an lxc container with the entire contents of that minipc in it.

I want to do this because I want to add that mini pc to my proxmox datacenter, but my friends don't want to lose their progress in the palworld server.

I've Used SCP to move files related to palworld over to a new Ubuntu LXC, but, though the pals and bases exist, the new server treats each of us like new players, not allowing us to claim the bases, items or pals we've gathered.
