The graphical workflow engine will continue to live on in the platform. There is no announcement to remove it. However, it will not be receiving any further updates or enhancements. The strategic direction for creating workflows is Flow Designer. Depending on your experience and investment, you may wish to continue maintaining existing workflows or assess the ability to migrate them (manually) to Flow Designer. The biggest mental hurdle I had was to stop thinking of Flow Designer as a replacement to Workflow. It is, sort of. Think of it more like Business Rules, scriptless scheduled jobs, and inbound notifications on super steroids.There's a trigger then a series of actions. I've seen customers with some pretty monolithic workflows (in the graphical workflow engine) that have a lot of script, loop all around and pretty much run until the record is closed. Flows can be more prescriptve, and thus easier to write and maintain, thus you can run then at specific points in your process flow. I recommend creating any new flows in Flow Designer.
