ARM Clone Multi-Node 11.1.2.3 environment

Hi,

We want to upgrade from 11.1.2.3.501 (multi-node environment) to 11.1.2.4 (multi-node). The documentation that I found explains how to upgrade an 11.1.2.4 multi-node environment, but for 11.1.2.3 only covers single-node environments. Are there any significant differences between 11.1.2.3 and 11.1.2.4 multi-node environments? Has anyone tried to perform the same update that we are looking to do? Is there any documentation that explains this process?

Thanks for sharing your thoughts,

Matt
