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
• Internal data disks
• 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 5-3 ).
• If possible, verify that you can start the applications you installed or upgraded.
• If possible, configure the settings for any applications you installed or upgraded.
If you are satisfied that everything is working correctly, you can merge the system to
stop your applications on the Production Side and restart them on the Upgrade Side for
final verification.
If there are any problems, you can abort the upgrade to return the system to its original
state. Aborting the upgrade while the system is in split mode does not incur downtime,
because your critical applications are still running on the Production Side.
