Changing Management Address on F5

I have been asked to change the MGMT IP address on two of our F5s that are in a HA pair. Will changing the IPs break any of the communications between the two or is the change communicated between the devices?

 

Thanks

    It depends how they are configured to do HA - do they have a separate VLAN/self-IP through which they communicate for network failover? If so then it should not cause an outage.

    Yes, It will break the communication and you might need to establish device trust also. Suggest you to change the mgmt IP during non-business hour.
