To upgrade to the latest version of QAD BI, upgrade one version at a time until you reach the current released version. For example, if you are using QAD BI 3.4.1 and are upgrading to QAD BI 3.7, first upgrade from BI 3.4.1 to 3.5, then upgrade from BI 3.5 to 3.6, and then upgrade from BI 3.6 to 3.7.
