Performing an upgrade pre-check
The pre-upgrade check determines if the system is ready for an upgrade. The pre-upgrade check runs automatically when you start the upgrade. The pre-upgrade check performs tests, which identify any potential problems that might result in an upgrade failure. You must resolve the issues before you upgrade the cluster.
Note:
Veritas recommends that you perform a pre-check one week in advance to ensure that you have sufficient time to fix any issues that are discovered during the pre-check. Additionally, run the pre-check again a day prior to the planned upgrade. The pre-check takes approximately 10 minutes to complete and does not require a scheduled downtime.
You can perform the pre-check using the Access Appliance UI or from the Appliance Shell Menu.
