This section explains how to perform a phased upgrade of VCS on four nodes with four service groups. Note that in this scenario, VCS and the service groups cannot stay online on the second subcluster during the upgrade of the second subcluster. Do not add, remove, or change resources or service groups on any nodes during the upgrade. These changes are likely to get lost after the upgrade.
An example of a phased upgrade follows. It illustrates the steps to perform a phased upgrade. The example makes use of a secure VCS cluster.
You can perform a phased upgrade from VCS 6.0 to VCS 7.3.
