В некоторых случаях требуется выгрузить и загрузить рабочий процесс Sharepoint 2013.

Это может потребоваться если нужно создать копию рабочего процесса для дальнейшей доработки.

Встроенных средств, осуществить это, найдено не было, но был найден скрипт для импорта и экспорта рабочих процессов.

 

Выгрузка рабочего процесса – ExtractWorkflowXaml.
