What will happen to existing ProcessMaker workflows in Sugar 7.6?

What will happen to existing ProcessMaker workflows (and licenses) once an instance of Sugar is upgraded to 7.6, with ProcessMaker built-in? Will the ProcessMaker module need to be uninstalled first? Will the workflows be lost, or is there a migration path?

We've not started using ProcessMaker yet, but would like to know if our work would be thrown away if we started using ProcessMaker for SugarCRM now.

(Currently on Sugar 7.2.2.0 Ent.)

Thank you,

Jason
