Backup cannot be restored on current device : Upgraded Hardware, both running 18.0.2 MR-2

Hi Joe DeVito,

Thank you for reaching out to the Community! 

Could you please share some detail about the old and upgraded hardware? 

Please check out the following KBA for more info: Sophos XG Firewall: Backup-restore compatibility check.

Thanks, 

Hi Joe,

you need to be running the same number of NICs.

Hey Ian,

If in fact that is true, I am guessing there is no way to edit the current config files to show less NICs?

OLD: 5 NIC (only using 4)

NEW: 4 NICs

Anyway to remove the old unused port from the config?

thanks again for your help, it's greatly appreciated 

Hi Joe,

no, the XG is not like the UTM. You could try disabling one NIC in BIOS and see if that works?

Good thing we are on the same page, i disabled a NIC, unfortunately because i am using a four port DELL card, i can only disable the onboard NIC, which is assigned to "Port5". This will work IF, big IF here, i can reassign Port5 settings to Port1? Or renumber the port settings? Being a Network engineer ive completed this task pretty easily, even on Linux distros.

I've looked through all CLI / Console configuration guides and i'm unable to find anything about "port reassignment" or "transferring port settings/configuration". I dropped into the Linux kernel to find i am unable to edit the network config file. This makes sense since this is a Sophos propitiatory version of Linux.

I guess the question is, how can i move my "LAN - Port5" to unassigned/unbound Port1?

I was even thinking, possibly i could add the current port to a LAG (Add Ports 1&5 to NEW LAG) then remove port 5 and the LAG while keeping their settings? Its a stretch but i'm at the end of mu rope here =)

Again, i really appreciate your help and guidance on this request

Hi Joe,

the XG will re-assign port 5 to a spare port assuming you are not using all ports? Your ports will all be renumbered i think based on MAC address order and PCI numbering.

so be prepared for a bit of confusion while you identify each port and reconnect them to the correct devices.

Ian

oh you are saying after i disable the the onboard NIC, it should have automatically reassigned from Port5 to the next available port? (Port1 is unassigned or bounded"

Because that didn't work =(

Hi Joe,

it should shuffle the order. Might take two restarts/power off for the change to be effective.

Ian

I made the change i nthe BIOS. Booted and shutdown 3 times in a row after the firewall entirely was up. The CLI login shows only 4 interfaces (used to say 5) so i know the disabling worked. But when looking at Network configuration, it still shows Port5 as the LAN and technically there is not a port 5 when i look at "show network interfaces".

Hi Joe,

which ones does it show as active?
