I am trying to fetch contents of a 2007 SharePoint site and trying to migrate those contents in my SharePoint Online. I am new to coding so I guess I am doing something wrong here. After Execute Query for source site, the debugger returns a 500 internal error. I am using windows form and credential passed for source is context.Credentials = CredentialCache.DefaultCredentials;
Error:
The remote server returned an error (500) Internal Server Error
