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 5-98 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.
