Change IP address in Central Management Settings
Hello everyone,
the FortiManager has 2 IP addresses and the FortiGate is authorized to IP 1 in the Security Fabric/Fabric Connectors/Central Management Settings but I need to change the authorization to IP 2. How do I do this?
If I use:
config sys central
set type none
end
config sys central
set type fortimanager
set fmg x.x.x.x
end
I remove the FortiGate from FortiManager and i have to remap the interfaces right? Is there an easier way?
Thank you

Hi @Alfonziino ,
Here are the steps to do this:
In FGT:
config sys central
set fmg "new IP"
end
Since the FGT already recognize the FMG SN, it can just reclaim the connection from FMG
In FMG:
exe fgfm reclaim-dev-tunnel
There will be no configuration lost for this steps, but the best practice is always perform a backup on both devices.

Hi @Alfonziino ,
The procedure you want to use seems correct (you could skip the first part anyway).
The following article can be helpful:

If I use the command:
config sys central
set type fortimanager
set fmg "new IP"
end
will I not lose the interface and configuration and the FortiGate will be authorized to the new IP address of the FortiManager? I'm a bit afraid of losing the configuration :(
Thx

You should not lose the FortiGate config on the FortiManager. On the FMG you can also retrieve the FGT config as soon as you have made the change.
Worst case scenario you could delete/re-authorise the FGT from the FMG.
