7.1rc6 Zerotier Address from backup

I’m using the RB450Gx4 with Zerotier. ZT is working great. No issues there. My issue is with backups and restoring to another device. I’m trying to setup multiple RB450Gx4’s, I set one up the way I need it, back it up, then restore on the other devices. One issue is that it’s restoring the same Zerotier address. So I have multiple routers with the same hardware address, therefore ZeroTier sees these as a single device. How do I create a new address to get ZT to see these devices as separate devices?
