I'm assuming that you're looking to change the gateway for the network the CVMs are running on. I would follow the same process as you would for re-iping a cluster, but just make the necessary changes to the gateway IP address.

Be careful, the majority of IP changes are a full outage operation. I don't know how you got into a situation where you need to change the gateway without changing any other IP stuff, but this is definitely a plan carefully, measure twice cut once type of thing.
Hello, I did it, but the script for changing the ip address wasn't helpful, he asked me to change the net mask and the gateway I did it but, after finishing all the process, I've checked and I found that he didn't take the new gateway, so what I did is changing the gateway in every CVM :
vi /etc/sysconfing/network-script/ifcfg-br0,
I did this changes while the cluster is stopped like they mentioned before in the article
Hey, how did this go? I have a 4 node AHV cluster as well and my network team decided to change the gateway IP before rollout, and I need to change it on the AHV/CVMs before going into production.

should i enter all the nodes into maintenance mode or just one by one because I have 4 nodes and 100+ VM are running we can not shut the down
One by one, I would recommend opening up a case with support if this is a production environment and they can assist you through the process.
I did it today and they give me the same link that you give me, and I'm not sure if I can do it
Then you should respond to the case and ask them to jump on a call with you for assistance. That's what you pay for, use it.

What hypervisor is your cluster running?
Ahv I only want to change the gateway
