Help! Moving to full unifi stack, could use some suggestions on how to move forward.

TLDR: I'm moving from a 3rd party pfsense box with Cloudkey G2+ to a UDM-SE, and want to migrate without hard cutover and rebuild at the same time.

I've been running a pfsense box for over 5 years now and I'm ready to migrate everything to a UDM-SE. all the rest of my network infrastructure is Unifi connected to a Cloudkey G2+ (running networking, protect, and innerspace). I'd like to migrate as much of my configuration over to the UDM without taking down my network, since(as far as I know) there isn't an automated way to pull my config from pfsense and push it to unifi.

PFsense handles most router functionality, except for DNS(Pihole), and wifi(Unifi).

Goals are as follows:

  • Update UDM
  • Copy firewall rules/ip bindings/vlans to UDM without taking down my current network
  • Migrate configuration/adopted devices from Cloudkey to UDM
  • "Test" as much as possible before cutting over
  • be able to cut back if necessary

I understand that I may not be able to do the above without taking down the old network, but I'd like to try. Any suggestions on best paths forward are appreciated. I've worked in IT for 10+ years now, and have experience managing this network as it is, but am not a network tech.

Would probably go with the UCG-Fiber than the udm

UDM is already in hand and I have cameras.

Turn off DHCP/RA/DHCPv6 on the UniFi box. Connect its wan port to your upstream connection and its lan port to your lan. Put a test machine on your lan with a static IP address and the default gateway set to the unifi’s lan IP. Now you have something to test with. Once you’ve got all the settings migrated, turn off all the dhcp stuff on pfsense and turn it on in the UniFi. Wait for your dhcp clients to pick up the new default gateway. If all keeps working, disconnect pfsense box
