FP4110 Outside interface IP address change

[williadc800]

We are changing our outside IP address range and I need to change the address on the interface, update the object IP addresses, update the global NAT, etc. on our FP4110.  Is there any advice from someone who has completed an external address change on an FP4110?  Is it a straightforward change the addresses in the various objects and the interface using FMC?  Thanks.

if your FMC have management connection, that is not what you changing, you are good.

Make sure you take backup and do in maintenance window, you expect break in the network.

if you have access to connected switch, you may clear arp entries depends on your switch configured,

if not mac address hold old IP address until clear the ARP expiry.
