Gathering Information

Before you start configuring the Active Upgrade process on your system, considering the following questions:
After you complete this upgrade, will you ever want to run the same type of upgrade again? If so, plan to create a
configuration file with the details of your upgrade, so you can use it again at a later date.
Did your support provider give you a configuration file that you could use as a template for your specific system
and the type of upgrade you are performing? Or, do you have settings from other existing configuration files that
you want to incorporate into your current configuration? (If applicable, you might be able to use more than one
configuration file at a time by nesting them).
Which disks in your system contain the software you want to upgrade? Which disks cannot or should not be
upgraded given the prerequisites of the Active Upgrade process? You will need to select these disks before
splitting the system.
Which software installation utilities are you going to run during the Active Upgrade process? (If you are copying
these to the system from a network resource, you need to do so before initiating split mode.) Do any of these
installer programs require access to the network or data disks during the upgrade? (If so, you cannot use them with
Active Upgrade technology.)
How do you start and stop critical applications on the system you want to upgrade? Are the applications configured
as services in the Services snap-in to Microsoft Management Console? Or do you need to run custom actions
(executables such as .bat, .vbs, .exe) to start your applications, possibly in a particular order? You need to identify
these services and custom actions during configuration to allow the Active Upgrade console to start and stop your
applications at the appropriate times during the upgrade process. See "Managing Critical Applications During the
Upgrade Process" on page 5-74 for more information.
Do you want to preserve Event Viewer log entries that are generated on the Production Side while the system is
running in split mode? These log entries are typically lost during the commit process, when the system
resynchronizes your RDR disks. If you want to save the files, you can configure the Active Upgrade console to
copy them to a backup directory before it commits the upgrade. You can save the standard log files as well as any
custom log files you have opened in the Event Viewer.
When you finish answering these questions, you can use the worksheet in Table 5- 1 to record your configuration
information.
