Upgrading from PReS Classic
PReS Classic and PReS Connect are very different products.
Whilst PReS Connect provides considerably more options for email and web output, one need not abandon existing PReS Classic print jobs. They can still be run through Connect Workflow, via the PReS Print Controls task in the Online Help of Workflow (see http://help.objectiflune.com/en/PReS-workflow-user-guide/2022.1/#Workflow/TasksProperties/PReS_Print_Control.html).
