is it possible to upgrade Nintex Workflow and Forms 2010 to 2016? Or is need a SharePoint 2013 Server? How i Migrate Workflows and Forms?
we follow the same migration path that Microsoft states with SharePoint. You will need to go through 2013 first.
I'm not sure, but ShareGate may support going 2010 -> 2016 directly. You could have a look at that too.
