How remove node from cluster in rhevm

Hello experts

I have 2 cluster of rhev. The first cluster have 4 nodes with rhev 3.5 and the second cluster have 5 nodes with RHEV 3.3. I need remove a node from cluster with RHEV 3.3, reinstall OS and re-assign the host to the cluster with rhev 3.5

I understand the procedure is the following

• Setting node in Maintenance
• Delete Node from cluster.

My questions is the following: I need other procedure by remove the node or only with the remove the cluster is sufficient.

Thanks for your comments
