Here it the process in Websphere Business Modeler .7.
I exported this model in .bpmn and uploaded it to Blueworks Live. Here it is the results.
The "Entrada" (Input) and "Salida" (Output) was not converted as I will like to.
What about if I export it as XPDL (used by Filenet) and import it to Blueworks Live.
Looks better, but I don't know what that "LaunchStep" is. It must be something specific about XPDL format.
I will keep trying with more complicated models.
