Preflight check before the upgrade

For upgrades to versions 2.7.1 and later, the upgrade script runs a preflight check to determine if the appliance is ready for an upgrade. The preflight check analyzes several system parameters and provides information about what was found and whether an upgrade can proceed. If the preflight check detects any issues that fail to meet the upgrade requirements, the upgrade is not allowed to proceed. You must address all of the reported issues before the upgrade is allowed.

Refer to the following topic for more information:

See Pre-upgrade tasks for appliance upgrades.


Upgrades to version 2.7.1 and later are not supported if you have installed Teradata binaries on the appliance. The RHEL operating system does not currently support the use of these binaries. The upgrade cannot proceed if the preflight check finds Teradata binaries on the appliance.
