After the upgrade, you must perform additional tasks to ensure that your ITMS 7.5 SP1 environment functions correctly. The tasks also let you revert to the ITMS environment configurations that you had set up before the upgrade. You use the Symantec Management Console of Notification Server to execute these tasks.
To ensure a successful upgrade to IT Management Suite 7.5 SP1
In the Symantec Management Console, click Settings, and compare the configuration settings to the ones you recorded when you prepared to upgrade.
Revert to the settings that you recorded while preparing to upgrade to ITMS 7.5 SP1 to keep your system running as it did before the upgrade.
If you had hierarchy implemented in your environment previously and had disabled the hierarchy during an upgrade, you must upgrade all the servers in the hierarchy.
The recommended practice is to upgrade Notification Servers starting from the lowest level to the highest level in the hierarchy. This means that you upgrade the lowest-level child Notification Servers and gradually upgrade the servers in the hierarchy till you reach the parent Notification Server. Ensure that each child Notification Server is upgraded to a higher version before its parent. You do not need to break any hierarchy relationships in the process. For more information, see www.symantec.com/docs/HOWTO21657.
Recreate a hierarchical relationship between Notification Servers in your environment, and enable the hierarchy replication that you had disabled before the upgrade.
