Pre-Upgrade Tasks
Preparing for the Active Upgrade Process 2-7
If your application runs as a standard service that already accounts for
interdependencies (with other services) and requires no special handling, you can
specify it on the
Application Services page of the Active Upgrade console during
the configuration process. On the Application Services page, you can select each
service you want to manage from the list of services on your system, and, when
you start the upgrade process, the Active Upgrade console automatically starts and
stops these services at the appropriate times. See
“Selecting Application Services
to Control” on page 3-9 for more information.

Custom actions
If you have a custom application or integrated applications from several different
software vendors, and you have special executable files that start and stop these
applications, you can specify the executable files on the
Custom Actions page of
the Active Upgrade console during the configuration process. Using the controls on
the
Custom Actions page, you can specify when your executable files will run
during the upgrade process, and, if you have several files, you can specify the order
in which they will run. See
“Configuring Custom Actions” on page 3-12 for more
information.
