In SharePoint Designer 2013 they have introduced a new
feature “Copy & Paste” for the workflow steps which will be very useful to
reduce the time in creating similar workflow steps. When I was trying to
explore that I just tried to copy and paste the SharePoint 2013 Workflow steps
into SharePoint 2010 workflow, I was getting the warning message as shown below
This is not supported in “Copy & Paste” functionality for
workflow steps. You will not be able to copy the SharePoint 2010 workflow steps
to SharePoint 2013 workflow or SharePoint
2013 workflow steps to SharePoint 2010 workflow.
