I'm doing SharePoint 2010 to SharePoint online migration. During migration I'm trying to do the user mapping for the account "NT Authority\Authenticated" and "NT AUTHORITY\LOCAL SERVICE".
From this post I came to know that "NT Authority\Authenticated" can be mapped with "Everyone except external users" in SharePoint online.
Can you please tell me what should be the mapping account for "NT AUTHORITY\LOCAL SERVICE" in SharePoint online and why?
Thanks in advance!!..
