A bit of a disappointment on not bringing over components, modules, and plugins. Using K2 (which I don't need any more with the new nested directories) I have quite a bit of work to do to get that into the article family.
It was very pleasant to get the latest version of Joomla installed and the articles moved over in a very quick and painless effort.
Thanks for the tool. We can't please all the people all the time and it does save a lot of up-front setup time.
