I would like to export the content of all blogs (excluding personal blogs) in SharePoint 2013 on prems. The purpose of that is to migrate later in a different platform. Is there any out of the box way to do that? In particular, is there any powershell script that gets the blog posts of each blog in every Site and store that in a file like txt, csv, xml or even docx?
I am not sure what is the target platform. I've already tried to search for an export to a general format but nothing came up. Using sharepoint paid addons is not an option at the moment. Thanks for your time.
