Verifying the success of your migration

Now that all nodes have been migrated, you need to complete the necessary tasks to ensure that everything is working correctly.

Verifying software levels installed using AIX commands
Verify the software installation by using the lppchk AIX® command, and check the installed directories to see that expected files are present.
Automatically saved files
Several files in the /usr/lpp/save.config directory are automatically saved during the upgrade process.
Verifying the upgraded cluster definition
After the upgraded PowerHA® SystemMirror® software is installed on all of the nodes in the cluster and cluster services are restored, verify and synchronize the cluster configuration. Verification ensures that the cluster definition is the same on all nodes. You can verify and synchronize a cluster only when all nodes in the cluster are running the same version of the software.
Verifying all cluster file sets have migrated
Previous documentation APARs might not be successfully converted resulting in the inability to synchronize the cluster.
Running AIX commands on the migrated cluster
To determine which daemons are active on a cluster node, you can use the options from the following SMIT menu, System Management (C-SPOC) > PowerHA® SystemMirror® Services > Show Cluster Services
