If the xSeries firewall needs to be factory reset the only way to get to the latest release is to upgrade through each release that has come in the past. To fix an issue Barracuda TAC suggested a factory rest of my x200 firewall, the unit reset itself back to 6.0.1.005 and it took almost 5 hours to get it back to 7.1.1.010. The xSeries firewall needs a way to be factory reset and get back to the latest release in a timely manner.

Another alternative is to support a backwards compatible config file starting with release 7.2 (as an example). This would also eventually solve this problem. If you have a backup that was from release 7.5 then you only need to get the FW back to release 7.2 to get it back up and running, because the 7.5 backup would load into a 7.2 release. Then the unit would be back in production and you could do upgrades at off times to get the unit up to the latest release then fully recover with original 7.5 backup, eventually shipping units with base OS 7.2 and solving the problem all together.
