To update Aster Analytics functions that are already installed, you must first uninstall them and then install their newer versions. Teradata recommends uninstalling the package that contains the older functions and then installing the package that contains the newer versions.
During this process, the functions are unavailable to users. If you want to maintain the older versions of the functions, install the new versions on a different schema.
This procedure is the recommended way to uninstall the package that contains the older functions and then install the package that contains the newer versions. Alternatively, you can use the ACT commands \remove and \install on each function. For information about ACT commands, see ACT Commands for Managing Files.
