5-148 Installing and Using Utilities
Managing Your Applications on the Production Side
While the system is split, you can continue to access and use your applications on the Production
Side; however,
you must avoid doing any of the following on the Production Side desktop:
•
Installing or upgrading software.
•
Creating or modifying any files on the system disk, including the system registry.
•
Restarting the operating system.
IMPORTANT:
„
Any changes you make to files on the Production Side system disks will be lost during the
commit process, because the system overwrites these system disks (which contain the old
version of your software) with the newer Upgrade Side disks to complete the upgrade. If you
need to preserve files from the original system disks, you can save them to a data disk.
„ Be careful when switching between the Production Side desktop and the remote connection to
the Upgrade Side desktop. When you resume software installation or restart the system, always
ensure that you are on the Upgrade Side.

Verifying the Upgrade Side Before Merging the System
After you have upgraded or installed software on the Upgrade Side, you can perform limited testing
on the Upgrade Side system disks, as long as your activities do not require access to the following
resources, which are currently unavailable:
•
Network
•
External storage
•
Application data disks
For example, you might want to perform the following tasks before you merge the system:
Verify the presence and version number of each software package (see “Verifying the Status of
Installed Software” on page 5-166).
If possible, verify that you can start the applications you installed or upgraded.
