Polling target on Serviceguard

Hi Guys,

we are planning to enable polling target on our SG in reference to this link

MC/ServiceGuard: Subnet Goes Down when one of the Cluster Node is Down - HP Customer Care (United States - English)

since our server is already in production can we apply the changes with ex. "cmapplyconf -v -C cmclconfig.ascii" without any downtime to SG?

From an old training manual I have, as of release 11.17 changing IP addresses for heartbeats or monitored subnets, requires the cluster to not be running.

The only cluster changes that could be made with the cluster running, were adding/deleting a node, changing max configured packages, and access control modifications.

If you have a newer version, I don't know what still applies.
