Moving OPNSense to new hardware

[sparticle]

I am looking at moving the network primary OPNSense Server to new hardware. The new hardware will have different NICS.

Testing this we took a back up of the config on the old OPNSense and did a S&R on the old interface names replacing any ref to the old LAN interface with the new one same for the WAN.

It boots fine and in an isolated network the interfaces look good. Everything is configured as per the old OPNSense server.

Unplugging the OLD server and plugging in the new one and powering up, the network is down. I thought it might be the mac tables that would need to sort themselves out etc. But after 30 mins even though showing as connected I could not access the GUI on the main switch.

What needs to be rebooted to make this work? Obviously the new OPNSense is powering up as if it was the old one. MAC addresses will be different I guess for the LAN and WAN interfaces.

Just wanting to try out new hardware and test. How do others do this?

I've done it just like that a few times. Search and replace exactly.
What did trip me once was the order was different i.e. igb1 became igc0 so WAN was not WAN anymore but LAN. That sort of thing.
What I did then was boot the new one and identify each nic how it was going to be enumerated. Then I knew how to do the correct search and replace. Maybe that?

Thanks for the note. The move seemed to go well. But the network is down. OPNSense is connected to the main switch. Rebooted the switch but doesn't seem to make any difference.

Reverted back to the old server and network up instantly.

Will check back through settings but they all seems ok.

Cheers

you're going to start hunting down for clues via console. Keyboard and monitor to the new hardware.

For good measure,  i usually go into each interface and specify "Prevent Interface Removal"
