I believe this is the latest upgrade tool for Firewall Enterprise to Next Gen Firewall:
These policy elements and configuration information are imported into the SMC.
- Network objects
- IP addresses
- IP address ranges
- Control Center adaptive objects
- Routing addresses
- VPN addresses
- Zones or burbs
- Zone groups or burb groups
As of right now, the rules are not imported. That will come in a later upgrade tool.
Is there any benefit to migrating from 8.3.2 to the NGFW software?
