Upgrading from the CLI

Upgrade HCL Workload Automation from the command-line interface.

The upgrade procedure varies depending on the product version you currently have installed:

if you have installed version 9.5.0.x or 10.x.x and want to upgrade to version 10.2.1 with a direct upgrade procedure, see Performing a direct upgrade from v 9.5.0.x or v 10.x.x to v 10.2.1.
if you have installed version 9.5.0.x or 10.x.x and want to upgrade to version 10.2.1 with a parallel upgrade procedure, see Parallel upgrade from v 9.5.0.x or version 10.x.x to v 10.2.1. This procedure might be useful when you have you have some of your components installed on operating systems which are no longer supported in version 10.2.1 and therefore cannot perform a direct upgrade.
if you have installed version 9.4.0.x and want to upgrade to version 10.2.1. In this case, only a parallel upgrade is supported. For more information, see Parallel upgrade from version 9.4.0.x to version 10.2.1.
