There are five types of upgrade you can do:

Each of these is discussed below.
Special Considerations for Upgrade to Serviceguard A.11.19
Serviceguard A.11.19 introduces a new cluster manager. In a running cluster, this affects
node timeout and failover and cluster re-formation; see the discussion of
MEMBER_TIMEOUT under “Cluster Configuration Parameters ” (page 139) for more
information. There is also a one-time effect on upgrade to Serviceguard A.11.19.
Upgrade will trigger a cluster membership transition from the old to the new cluster
manager when the last node in the cluster has been upgraded to A.11.19. This transition
can take up to one second, during which time the old cluster manager will shut down
and the new cluster manager will start.
