I am migrating sites from frontpage to Joomla. Some of the sits are large enough that it will take a week or so to migrate
The problem I have is that I don't want duplicate content. I don't want to just make the site 'unpublished' in joomla and I don't quite trust robots.txt.
What I am considering is setting all of the articles to 'registered only' so that only registered users can see the new site. That should keep the googlebot from seeing the site since I won't supply the credentials to google sitemap.
When I am ready to make the migration, I get rid of the old site and change the public side of the new site to 'public'.
I think that would be an relatively manageable way to handle the migration and prevent duplicate content penaltied (and user confusion between the old and new sites)
I'm just wondering if I am overlooking anything here.
