I need to create workflow for fulfill following task:
'Copy document from Document Set to another Document Set'
Here are the extra details :
Site Collection 1: Library A > Document Set Aa > Document Abb
Site Collection 2: Library B > Document Set Aa >
Requirement: Copy 'Document Abb' From 'Site Collection 1' to 'Site Collection 2'
Have you got any idea to do this?
This seems to be your scenario Nintex Workflow - Move Documents and Preserve Version History - Vadim Tabakman
Where he is moving a document from one Doc Set to another and preserving history using the Author.dll features in SP on prem. Otherwise you can use the actions
Copy to SharePoint, or
Call Web Service -> Copy.asmx
An discussion using these actions is here How to move documents sets from library to library
Hope that helps!
