There is a tool move Objects/Rules from 3rd party vendors to Check Point - Smart Move (https://github.com/CheckPointSW/SmartMove or sk115416). Currently only firewalls from Cisco, Juniper, Fortinet and Palo Alto are supported. Maybe the code from github can be modified to work with Barracuda, but I'm not sure if this is more efficent than a manual migration.
You could also do a little house cleaning on the barracuda before you migrate the configuration, often several rules can be combined into one or old objects might not be needed anymore. The more you clean up the less you have to migrate.
