Beginning in OnBase Foundation EP5, the OnBase Client Classic Workflow interface is no longer supported and has been removed from the Workflow module. If you are using the Classic Workflow interface and upgrading to OnBase Foundation 22.1, you will be required to use the Core-based interfaces in the OnBase Client, Web Client, or Unity Client to fulfill your needs.
With the removal of the Classic Workflow interface, an Application Server is required for all Workflow processing other than import processing performed via the OnBase Client (for example, scan queues, DIP, or COLD processing). If the Add Documents to Workflow option is selected for an OnBase Client import process, the documents are added, but no system work processing occurs. The Perform System Work option is still available for selection, but it is only respected with a connected Application Server.
