Did you upgraded first to 2013 and then to 2016 right ? Is it a 2010 / 2013 workflow ? If it's 2010 workflow make sure you publish the workflow and clear the cache and try again. If it's 2013 workflow do you have workflow manager configured for SP 2016 ? If you did make sure you publish the workflow and try it again.

Thanks & Regards,
