You can upgrade a cluster from OES 2 SP3 to OES 2015 or later. The same release version of OES 2015 or later must be installed and running on each new or upgraded node in the cluster.
The procedure in this section refers to OES 2015 or later.
If you replace an OES 2 SP3 node with an OES 2015 or later node instead of using an in-place upgrade to OES 2015 or later, you must manually configure the global policies and move the All Shadowed Volumes policies data to the OES 2015 or later node.
On the replacement OES 2015 or later node, set the same global configuration policies that are set on the OES 2 SP3 nodes.
If you have All Shadowed Volumes policies set on the OES 2 SP3 nodes, copy the information in the /usr/novell/sys/._NETWARE/shadow_policy.xml file to the same path on the replacement OES 2015 or later nodes.
In iManager, use the Clusters plug-in to modify the preferred nodes list for each DST pool cluster resource to specify only OES 2015 or later nodes as fail-over candidates.
Launch a terminal console, then cluster migrate the DST pool cluster resource to an OES 2015 or later node:
cluster migrate <dst_volume_cluster_resource> [oes2015_node_name]
If the node name is not specified, the resource automatically is brought online on an available node in its preferred nodes list. To bring it online on a specific node, you can specify a node in its preferred nodes list. The resource will be mounted there if it is possible to do so; that is, if the node is available and there are no resource conflicts.
