Online migration 12.3 --> 12.5 & cluster


I’ve got a two node cluster productive with 12.3 release. I need to update to 12.5 due our software requirement. I’ve already migrate from Yast development and test servers (no cluster) without problem. So now we will update production enviroment. Is there any particular procedure for cluster? Do i have to pay attention to something in particular? Will the cluster configuration be maintained? Unfortunately I am not very expert on the cluster.

Thank you so much.
