HA - Can I simply change the IP address in the peer administration setting afterwards?

Hello everyone,

I have a quick question regarding the HA combination of two XGS2100s. A customer has an active-passive HA. There are two interfaces in the peer administration settings. One is a management port and the other is port 1, but I cannot reach the passive firewall via either IP address using SSH via Putty.

Some time ago, the network at port 1 changed. Before it was 192.168.116.0/24 and now it is 192.168.110.0/24.
In the peer administration settings, however, the IP 192.168.116.254 is still entered for Port1. Now to the actual question. Can I simply change the IP address in the peer administration setting, or will I have a problem with the HA?

Or is there something to consider?
