Hey Amir,
Just wanted to update this thread with info we got from TAC. Customer replaced their old 700 smb with new 2500 series and one of my colleagues was helping them, but we never realized it was not supported to copy the config from show config output between smb appliances, as you normally can do with regular Gaia firewalls,.
Anyhow, this did "work", but why I used quotes when I say that, is because new box seemed to respond, remote access vpn also functioned, but then next day, when customer logged into the web UI, they noticed when clicking on random tabs on the left, would give pop up error (cant recall what it said though). We thought, maybe updating to R82 version would make sense, but when we called TAC, engineer told us that method we used to copy the config most likely caused database errors issue and also informed us there are some known issues with R82 as well and she would not recommend upgrading to it, as its highly unlikely it would fix the problem.
At this time, my colleague will get the device client will bring to our office, she will factory reset it and then configure from scratch. For now, they will use their old 700 series, hopefully only few days.
Just wanted to provide that feedback.
The silver lining (if you will) in this case is that this is very small place (maybe only 10 - 15 people), so they dont mind using an old box again, but its definitely good to know method we used to copy the config would cause database errors.
Certainly something to be aware of next time.
Best,
Andy
