Change FC Group IP Address

I have a 3 node failover cluster that I think needs an IP address change because the current cluster IP address is on my Node Management network.

Here is my network config:

FC Internal Communication
10.24.24.0/24, Cluster Use: Internal

FC Live Migration
10.25.25.0/24, Cluster Use: Internal

iSCSI Traffic
10.23.23.0/24 Cluster Use: Disabled

Node Management
10.20.20.0/24 Cluster Use: Enabled (also allows clients to connect

The cluster IP Address is 10.20.20.200, which of course means it sits on the Node Management network.

I want to disallow cluster use of the Node Management network, but that network hold the IP Address of my failover cluster, so as soon as stop allowing cluster network communication on that network, my cluster IP Address fails

Is it best practice to have the cluster IP address set on a network dedicated to cluster communication?  If so, how can I change the address of a running cluster?

Thanks for any help you can offer,
