Change the licensing update so you do not have to disable clustering to update your licenses. It should be able to pre-check the licenses from the primary node, validate the new license files and update the cluster.
Hi Robert. PAM is designed to require that the licenses match in order for a cluster to be started. Obviously, changing a license on a running cluster member would violate this requirement. If you feel strongly that this change be made, please create an Enhancement Request, as an Idea in the PAM community.
