To perform an in-place upgrade on non-clustered 64-bit environments, simply run the Workflow Automation setup program on your existing Workflow Automation computers. It is not necessary to stop any Workflow Automation services that may be running.
Note: Any Workflow Automation adapters that are not built-in to the Workflow Automation installer must be uninstalled and reinstalled post-upgrade.
For more detailed information about upgrading Workflow Automation, see Upgrading from a Previous Version
in the Workflow Automation Administrator Guide.
