Why doesn't my Web Security Gateway firmware backup accept my backup file to restore?

We have found that some firmware versions do not accept backup configuration files, especially when previous generation platform/firmware versions are used. This then turns into a manual process to restore configuration.

We will look into documenting this, and try to provide a tool to migrate across firmware versions in the future.

We have created a feature request and the reference number is BNYF-9792.
Starting with Firmware 9.1 and onwards, backups are forwards-compatible.
