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

I wanted to upgrade my hardware from a big PC to a small networking unit. Read all reviews and made sure i am running the same EXACT firmware on both. I have months worth of backups and when i attempt to restore ANY of them to the NEW registered device, it states :Backup cannot be restored on this Device

I've verified all patterns are the same versions as well, what am i missing here?

  • It shows Port1-Port4 active without a Port5 from the console "show network interfaces". But when i select 1 Devie Interfaces it still shows Port5 as LAN.

  • Hi Joe,

    I think we need a wizkid to jump in here and help out?

  • if possible that would be fantastic!

  • I went on a 5 hour troubleshooting session till 2AM my time and i was able to figure out a work around.

    - I reset my device back to factory defaults with 5 NICs (Onboard not disabled). Applied backup config and during the reload into the firmware, i disabled the NIC hoping it would reassign, i did not

    - I shutdown fully three times and still the "LAN" zone was assign to Port5. Port5 however is not shown in "show network interfaces" and Port1 shows "UNBOUND"

    - I attempted to rename the "Port5" interface to "Inside" in case it was holding the name and getting confused. Unfortunately after multiple shutdowns, this did not help

    At this point, i started to focus more on the security zone "LAN" and not the interface because Sophos binds all of it's components on the security zone and not interface. 

    Here is how i resolved my issue (Which was the interface count as suggested by Ian)

    I changed the "LAN" security zone's IP from .254 to .250. Reconnected over .250, Configured Port1 on the same "LAN" zone with .254. I was surprised the Firewall allowed me to configure the same zone and subnet on another interface but this allowed the security zone to stay active in 2 places. I then deleted Port5 and everything was still up and running, At this point i was left with Port1-4 configured, active and working. On the next reload, i disabled the on board NIC and after boot up, Port5 was gone leaving me with 4 Network interfaces!!!! (Port1-Port4)

    Created a new backup, applied this backup to the NEW device and i am happy to say i am up and running with minimal configuration to complete this task.

    It was a battle but the work around was not only informative, but i was able to complete the migration which in the end, was the point.

    Thank you Ian.  I work for an IT MSP so i appreciate not only your helpfulness, but were extremely responsive which is the hardest part of support. So again thank you!
