Pre-Upgrade Tasks
Preparing for the Active Upgrade Process 2-1 5
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 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 installation 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 (executable files
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 2-6 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 2-1 to
record your configuration information.
