Fortinet Firewall Migration
Our Old Firewall has been in service since 2013 and is on the last support cycle before End of Life. We needed to replace the Firewall including getting the code and config compatible with the new FortiOS.
TimeLine
Project Started on May 2021 and completed on August 2021. No downtime reported and the only blip happened on the cutover day which lasted around 5 minutes until all ARP Cache for MAC has cleared.
Before Migration Diagram
We are running an HA Fortinet Cluster. No VDOMs and both firewall physically separated between 2 buildings. HA Heartbeat connected through VLAN
After Migration Diagram
We moved both nodes in Annenberg Building, use direct HA Heartbeat connections. Use VDOM for configuration.
