NetIQ Corporation recommends upgrading AppManager components in the following order:
Primary QDB
Management server
Windows agent
Task Scheduler service
Modules
CCDB
Before you upgrade the CCDB, ensure that it does not contain any QDBs that are earlier than version 9.1. If it does, either remove the QDBs or upgrade them to version 9.1.
Control Center and Deployment services
Control Center console
Non-primary QDBs
Operator Console
Jobs
When you start the Control Center console, if derived Knowledge Scripts or ad hoc jobs are pending propagation, you are prompted to start the Knowledge Script Propagation wizard. The wizard allows you to select the scripts and ad hoc jobs to process. For more information about using the wizard, see Manually Propagating a base Knowledge Script to Derived Knowledge Scripts and Ad Hoc Jobs in the Control Center User Guide for AppManager.
For the computer on which you run the setup program, the program automatically detects the components available for upgrade and upgrades those components in the recommended order. If you are upgrading components on multiple computers, schedule the upgrades according to the recommended order. For example, if you are upgrading the management server and agent on different computers, run the setup program on the management server before you run it on the agent computer.
If you do not upgrade Control Center components in the recommended order, the Deployment Service will not start after the upgrade.
