We have a SharePoint 2013 on premise environment.
I need to move some sub sites (spweb's) and their content, including the unique permissions, over to another site collection.
I have not found suitable powershell or GUI commands I can apply for my purpose. Is this possible with powershell or SharePoint GUI? Or do I have to use a 3rd party tool? Please advice.
If you know about any good tools I can use then please let me know.
